Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163630, here are decompositions:

  • 3 + 163627 = 163630
  • 17 + 163613 = 163630
  • 29 + 163601 = 163630
  • 113 + 163517 = 163630
  • 149 + 163481 = 163630
  • 197 + 163433 = 163630
  • 227 + 163403 = 163630
  • 263 + 163367 = 163630

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 163,630 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 163630 first appears in π at position 77,927 of the decimal expansion (the 77,927ordinal-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.
