Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38040, here are decompositions:

  • 29 + 38011 = 38040
  • 43 + 37997 = 38040
  • 47 + 37993 = 38040
  • 53 + 37987 = 38040
  • 73 + 37967 = 38040
  • 83 + 37957 = 38040
  • 89 + 37951 = 38040
  • 151 + 37889 = 38040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38040 first appears in π at position 70,363 of the decimal expansion (the 70,363ordinal-suffix:rd 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.
