Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153554, here are decompositions:

  • 31 + 153523 = 153554
  • 43 + 153511 = 153554
  • 67 + 153487 = 153554
  • 97 + 153457 = 153554
  • 127 + 153427 = 153554
  • 211 + 153343 = 153554
  • 241 + 153313 = 153554
  • 277 + 153277 = 153554

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 153,554 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 153554 first appears in π at position 493,966 of the decimal expansion (the 493,966ordinal-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.
