Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123020, here are decompositions:

  • 3 + 123017 = 123020
  • 13 + 123007 = 123020
  • 19 + 123001 = 123020
  • 67 + 122953 = 123020
  • 151 + 122869 = 123020
  • 181 + 122839 = 123020
  • 193 + 122827 = 123020
  • 277 + 122743 = 123020

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 123,020 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 123020 first appears in π at position 377,346 of the decimal expansion (the 377,346ordinal-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.
