Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155054, here are decompositions:

  • 7 + 155047 = 155054
  • 37 + 155017 = 155054
  • 73 + 154981 = 155054
  • 127 + 154927 = 155054
  • 157 + 154897 = 155054
  • 181 + 154873 = 155054
  • 307 + 154747 = 155054
  • 331 + 154723 = 155054

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 155,054 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 155054 first appears in π at position 415,614 of the decimal expansion (the 415,614ordinal-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.
