Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531950, here are decompositions:

  • 31 + 531919 = 531950
  • 73 + 531877 = 531950
  • 79 + 531871 = 531950
  • 103 + 531847 = 531950
  • 109 + 531841 = 531950
  • 127 + 531823 = 531950
  • 151 + 531799 = 531950
  • 157 + 531793 = 531950

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 531,950 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 531950 first appears in π at position 510,334 of the decimal expansion (the 510,334ordinal-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.
