Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16178, here are decompositions:

  • 37 + 16141 = 16178
  • 67 + 16111 = 16178
  • 109 + 16069 = 16178
  • 241 + 15937 = 16178
  • 271 + 15907 = 16178
  • 277 + 15901 = 16178
  • 439 + 15739 = 16178
  • 499 + 15679 = 16178

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16178 first appears in π at position 119,714 of the decimal expansion (the 119,714ordinal-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.
