Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31194, here are decompositions:

  • 5 + 31189 = 31194
  • 11 + 31183 = 31194
  • 13 + 31181 = 31194
  • 17 + 31177 = 31194
  • 41 + 31153 = 31194
  • 43 + 31151 = 31194
  • 47 + 31147 = 31194
  • 71 + 31123 = 31194

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31194 first appears in π at position 29,707 of the decimal expansion (the 29,707ordinal-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.
