Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556580, here are decompositions:

  • 7 + 556573 = 556580
  • 43 + 556537 = 556580
  • 61 + 556519 = 556580
  • 67 + 556513 = 556580
  • 97 + 556483 = 556580
  • 103 + 556477 = 556580
  • 139 + 556441 = 556580
  • 181 + 556399 = 556580

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 556,580 and was likely granted around 1895.

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

Position in π

The digit sequence 556580 first appears in π at position 156,894 of the decimal expansion (the 156,894ordinal-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.
