Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40122, here are decompositions:

  • 11 + 40111 = 40122
  • 23 + 40099 = 40122
  • 29 + 40093 = 40122
  • 59 + 40063 = 40122
  • 83 + 40039 = 40122
  • 109 + 40013 = 40122
  • 113 + 40009 = 40122
  • 139 + 39983 = 40122

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40122 first appears in π at position 141,374 of the decimal expansion (the 141,374ordinal-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.
