Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19168, here are decompositions:

  • 5 + 19163 = 19168
  • 11 + 19157 = 19168
  • 29 + 19139 = 19168
  • 47 + 19121 = 19168
  • 89 + 19079 = 19168
  • 131 + 19037 = 19168
  • 137 + 19031 = 19168
  • 167 + 19001 = 19168

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19168 first appears in π at position 195,341 of the decimal expansion (the 195,341ordinal-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.
