Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45140, here are decompositions:

  • 3 + 45137 = 45140
  • 13 + 45127 = 45140
  • 19 + 45121 = 45140
  • 79 + 45061 = 45140
  • 127 + 45013 = 45140
  • 157 + 44983 = 45140
  • 181 + 44959 = 45140
  • 223 + 44917 = 45140

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45140 first appears in π at position 47,816 of the decimal expansion (the 47,816ordinal-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.
