Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40172, here are decompositions:

  • 3 + 40169 = 40172
  • 19 + 40153 = 40172
  • 43 + 40129 = 40172
  • 61 + 40111 = 40172
  • 73 + 40099 = 40172
  • 79 + 40093 = 40172
  • 109 + 40063 = 40172
  • 163 + 40009 = 40172

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40172 first appears in π at position 161,380 of the decimal expansion (the 161,380ordinal-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.
