Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38090, here are decompositions:

  • 7 + 38083 = 38090
  • 37 + 38053 = 38090
  • 43 + 38047 = 38090
  • 79 + 38011 = 38090
  • 97 + 37993 = 38090
  • 103 + 37987 = 38090
  • 127 + 37963 = 38090
  • 139 + 37951 = 38090

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 38090 first appears in π at position 212,771 of the decimal expansion (the 212,771ordinal-suffix:st 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.
