Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154994, here are decompositions:

  • 3 + 154991 = 154994
  • 13 + 154981 = 154994
  • 61 + 154933 = 154994
  • 67 + 154927 = 154994
  • 97 + 154897 = 154994
  • 241 + 154753 = 154994
  • 271 + 154723 = 154994
  • 313 + 154681 = 154994

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 154,994 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 154994 first appears in π at position 542,772 of the decimal expansion (the 542,772ordinal-suffix:nd 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.
