Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556490, here are decompositions:

  • 3 + 556487 = 556490
  • 7 + 556483 = 556490
  • 13 + 556477 = 556490
  • 31 + 556459 = 556490
  • 139 + 556351 = 556490
  • 163 + 556327 = 556490
  • 211 + 556279 = 556490
  • 223 + 556267 = 556490

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 556,490 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 556490 first appears in π at position 732,804 of the decimal expansion (the 732,804ordinal-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.
