Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38020, here are decompositions:

  • 23 + 37997 = 38020
  • 29 + 37991 = 38020
  • 53 + 37967 = 38020
  • 113 + 37907 = 38020
  • 131 + 37889 = 38020
  • 149 + 37871 = 38020
  • 167 + 37853 = 38020
  • 173 + 37847 = 38020

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38020 first appears in π at position 76,764 of the decimal expansion (the 76,764ordinal-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.
