Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17838, here are decompositions:

  • 11 + 17827 = 17838
  • 31 + 17807 = 17838
  • 47 + 17791 = 17838
  • 89 + 17749 = 17838
  • 101 + 17737 = 17838
  • 109 + 17729 = 17838
  • 131 + 17707 = 17838
  • 157 + 17681 = 17838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17838 first appears in π at position 25,998 of the decimal expansion (the 25,998ordinal-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.
