Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757490, here are decompositions:

  • 3 + 8757487 = 8757490
  • 17 + 8757473 = 8757490
  • 101 + 8757389 = 8757490
  • 113 + 8757377 = 8757490
  • 149 + 8757341 = 8757490
  • 227 + 8757263 = 8757490
  • 281 + 8757209 = 8757490
  • 311 + 8757179 = 8757490

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 8,757,490 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 8757490 first appears in π at position 534,161 of the decimal expansion (the 534,161ordinal-suffix:st 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.
