Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169530, here are decompositions:

  • 7 + 169523 = 169530
  • 29 + 169501 = 169530
  • 37 + 169493 = 169530
  • 41 + 169489 = 169530
  • 47 + 169483 = 169530
  • 59 + 169471 = 169530
  • 73 + 169457 = 169530
  • 103 + 169427 = 169530

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 169,530 and was likely granted around 1874.

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

Position in π

The digit sequence 169530 first appears in π at position 588,559 of the decimal expansion (the 588,559ordinal-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.
