Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548138, here are decompositions:

  • 79 + 548059 = 548138
  • 139 + 547999 = 548138
  • 181 + 547957 = 548138
  • 229 + 547909 = 548138
  • 307 + 547831 = 548138
  • 397 + 547741 = 548138
  • 457 + 547681 = 548138
  • 499 + 547639 = 548138

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 548,138 and was likely granted around 1895.

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

Position in π

The digit sequence 548138 first appears in π at position 952,897 of the decimal expansion (the 952,897ordinal-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.
