Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38838, here are decompositions:

  • 5 + 38833 = 38838
  • 17 + 38821 = 38838
  • 47 + 38791 = 38838
  • 71 + 38767 = 38838
  • 89 + 38749 = 38838
  • 101 + 38737 = 38838
  • 109 + 38729 = 38838
  • 127 + 38711 = 38838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38838 first appears in π at position 98,691 of the decimal expansion (the 98,691ordinal-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.
