Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128054, here are decompositions:

  • 7 + 128047 = 128054
  • 103 + 127951 = 128054
  • 181 + 127873 = 128054
  • 211 + 127843 = 128054
  • 307 + 127747 = 128054
  • 337 + 127717 = 128054
  • 373 + 127681 = 128054
  • 397 + 127657 = 128054

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 128,054 and was likely granted around 1872.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 128054 first appears in π at position 946,601 of the decimal expansion (the 946,601ordinal-suffix:st 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.
