Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16824, here are decompositions:

  • 13 + 16811 = 16824
  • 37 + 16787 = 16824
  • 61 + 16763 = 16824
  • 83 + 16741 = 16824
  • 131 + 16693 = 16824
  • 151 + 16673 = 16824
  • 163 + 16661 = 16824
  • 167 + 16657 = 16824

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16824 first appears in π at position 217,938 of the decimal expansion (the 217,938ordinal-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.
