Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39838, here are decompositions:

  • 11 + 39827 = 39838
  • 17 + 39821 = 39838
  • 47 + 39791 = 39838
  • 59 + 39779 = 39838
  • 89 + 39749 = 39838
  • 167 + 39671 = 39838
  • 179 + 39659 = 39838
  • 257 + 39581 = 39838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 39838 first appears in π at position 47,259 of the decimal expansion (the 47,259ordinal-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.
