Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531118, here are decompositions:

  • 17 + 531101 = 531118
  • 47 + 531071 = 531118
  • 101 + 531017 = 531118
  • 149 + 530969 = 531118
  • 257 + 530861 = 531118
  • 281 + 530837 = 531118
  • 311 + 530807 = 531118
  • 449 + 530669 = 531118

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 531,118 and was likely granted around 1894.

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

Position in π

The digit sequence 531118 first appears in π at position 411,147 of the decimal expansion (the 411,147ordinal-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.
