Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153992, here are decompositions:

  • 43 + 153949 = 153992
  • 79 + 153913 = 153992
  • 103 + 153889 = 153992
  • 151 + 153841 = 153992
  • 229 + 153763 = 153992
  • 463 + 153529 = 153992
  • 523 + 153469 = 153992
  • 571 + 153421 = 153992

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 153,992 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 153992 first appears in π at position 785,065 of the decimal expansion (the 785,065ordinal-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.
