Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38100, here are decompositions:

  • 17 + 38083 = 38100
  • 31 + 38069 = 38100
  • 47 + 38053 = 38100
  • 53 + 38047 = 38100
  • 61 + 38039 = 38100
  • 89 + 38011 = 38100
  • 103 + 37997 = 38100
  • 107 + 37993 = 38100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38100 first appears in π at position 251,312 of the decimal expansion (the 251,312ordinal-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.
