Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755580, here are decompositions:

  • 79 + 8755501 = 8755580
  • 181 + 8755399 = 8755580
  • 199 + 8755381 = 8755580
  • 241 + 8755339 = 8755580
  • 283 + 8755297 = 8755580
  • 313 + 8755267 = 8755580
  • 349 + 8755231 = 8755580
  • 439 + 8755141 = 8755580

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,755,580 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8755580 first appears in π at position 131,270 of the decimal expansion (the 131,270ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
