Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124028, here are decompositions:

  • 7 + 124021 = 124028
  • 31 + 123997 = 124028
  • 97 + 123931 = 124028
  • 199 + 123829 = 124028
  • 211 + 123817 = 124028
  • 241 + 123787 = 124028
  • 271 + 123757 = 124028
  • 367 + 123661 = 124028

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 124,028 and was likely granted around 1871.

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

Position in π

The digit sequence 124028 first appears in π at position 474,829 of the decimal expansion (the 474,829ordinal-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.
