Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556018, here are decompositions:

  • 11 + 556007 = 556018
  • 191 + 555827 = 556018
  • 251 + 555767 = 556018
  • 257 + 555761 = 556018
  • 311 + 555707 = 556018
  • 347 + 555671 = 556018
  • 461 + 555557 = 556018
  • 557 + 555461 = 556018

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 556,018 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 556018 first appears in π at position 812,799 of the decimal expansion (the 812,799ordinal-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.
