Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531992, here are decompositions:

  • 3 + 531989 = 531992
  • 73 + 531919 = 531992
  • 151 + 531841 = 531992
  • 193 + 531799 = 531992
  • 199 + 531793 = 531992
  • 379 + 531613 = 531992
  • 421 + 531571 = 531992
  • 661 + 531331 = 531992

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 531,992 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 531992 first appears in π at position 336,738 of the decimal expansion (the 336,738ordinal-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.
