Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19370, here are decompositions:

  • 37 + 19333 = 19370
  • 61 + 19309 = 19370
  • 97 + 19273 = 19370
  • 103 + 19267 = 19370
  • 139 + 19231 = 19370
  • 151 + 19219 = 19370
  • 157 + 19213 = 19370
  • 163 + 19207 = 19370

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19370 first appears in π at position 68,234 of the decimal expansion (the 68,234ordinal-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.
