Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153660, here are decompositions:

  • 11 + 153649 = 153660
  • 19 + 153641 = 153660
  • 37 + 153623 = 153660
  • 53 + 153607 = 153660
  • 71 + 153589 = 153660
  • 97 + 153563 = 153660
  • 103 + 153557 = 153660
  • 127 + 153533 = 153660

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 153,660 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 153660 first appears in π at position 296,911 of the decimal expansion (the 296,911ordinal-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.
