Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555646, here are decompositions:

  • 53 + 555593 = 555646
  • 89 + 555557 = 555646
  • 227 + 555419 = 555646
  • 263 + 555383 = 555646
  • 353 + 555293 = 555646
  • 359 + 555287 = 555646
  • 389 + 555257 = 555646
  • 479 + 555167 = 555646

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 555,646 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 555646 first appears in π at position 118,765 of the decimal expansion (the 118,765ordinal-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.
