Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41808, here are decompositions:

  • 7 + 41801 = 41808
  • 31 + 41777 = 41808
  • 37 + 41771 = 41808
  • 47 + 41761 = 41808
  • 71 + 41737 = 41808
  • 79 + 41729 = 41808
  • 89 + 41719 = 41808
  • 127 + 41681 = 41808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 41808 first appears in π at position 31,141 of the decimal expansion (the 31,141ordinal-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.
