Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531768, here are decompositions:

  • 37 + 531731 = 531768
  • 67 + 531701 = 531768
  • 79 + 531689 = 531768
  • 101 + 531667 = 531768
  • 131 + 531637 = 531768
  • 137 + 531631 = 531768
  • 157 + 531611 = 531768
  • 179 + 531589 = 531768

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 531,768 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 531768 first appears in π at position 447,738 of the decimal expansion (the 447,738ordinal-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.
