Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40108, here are decompositions:

  • 71 + 40037 = 40108
  • 137 + 39971 = 40108
  • 179 + 39929 = 40108
  • 239 + 39869 = 40108
  • 251 + 39857 = 40108
  • 269 + 39839 = 40108
  • 281 + 39827 = 40108
  • 317 + 39791 = 40108

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40108 first appears in π at position 50,829 of the decimal expansion (the 50,829ordinal-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.
