Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40194, here are decompositions:

  • 5 + 40189 = 40194
  • 17 + 40177 = 40194
  • 31 + 40163 = 40194
  • 41 + 40153 = 40194
  • 43 + 40151 = 40194
  • 67 + 40127 = 40194
  • 71 + 40123 = 40194
  • 83 + 40111 = 40194

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40194 first appears in π at position 23,281 of the decimal expansion (the 23,281ordinal-suffix:st 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.
