Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145832, here are decompositions:

  • 3 + 145829 = 145832
  • 13 + 145819 = 145832
  • 61 + 145771 = 145832
  • 73 + 145759 = 145832
  • 79 + 145753 = 145832
  • 109 + 145723 = 145832
  • 151 + 145681 = 145832
  • 199 + 145633 = 145832

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 145,832 and was likely granted around 1873.

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

Position in π

The digit sequence 145832 first appears in π at position 468,122 of the decimal expansion (the 468,122ordinal-suffix:nd 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.
