Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 556530, here are decompositions:

  • 11 + 556519 = 556530
  • 17 + 556513 = 556530
  • 43 + 556487 = 556530
  • 47 + 556483 = 556530
  • 53 + 556477 = 556530
  • 71 + 556459 = 556530
  • 89 + 556441 = 556530
  • 127 + 556403 = 556530

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 556,530 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 556530 first appears in π at position 556,676 of the decimal expansion (the 556,676ordinal-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.
