Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531184, here are decompositions:

  • 11 + 531173 = 531184
  • 41 + 531143 = 531184
  • 83 + 531101 = 531184
  • 113 + 531071 = 531184
  • 167 + 531017 = 531184
  • 347 + 530837 = 531184
  • 431 + 530753 = 531184
  • 443 + 530741 = 531184

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 531,184 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 531184 first appears in π at position 146,496 of the decimal expansion (the 146,496ordinal-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.
