Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19750, here are decompositions:

  • 11 + 19739 = 19750
  • 23 + 19727 = 19750
  • 41 + 19709 = 19750
  • 53 + 19697 = 19750
  • 89 + 19661 = 19750
  • 167 + 19583 = 19750
  • 173 + 19577 = 19750
  • 179 + 19571 = 19750

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19750 first appears in π at position 39,897 of the decimal expansion (the 39,897ordinal-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.
