Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154738, here are decompositions:

  • 5 + 154733 = 154738
  • 11 + 154727 = 154738
  • 47 + 154691 = 154738
  • 71 + 154667 = 154738
  • 149 + 154589 = 154738
  • 167 + 154571 = 154738
  • 251 + 154487 = 154738
  • 461 + 154277 = 154738

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 154,738 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 154738 first appears in π at position 725,830 of the decimal expansion (the 725,830ordinal-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.
