Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66846, here are decompositions:

  • 5 + 66841 = 66846
  • 37 + 66809 = 66846
  • 83 + 66763 = 66846
  • 97 + 66749 = 66846
  • 107 + 66739 = 66846
  • 113 + 66733 = 66846
  • 149 + 66697 = 66846
  • 163 + 66683 = 66846

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66846 first appears in π at position 50,021 of the decimal expansion (the 50,021ordinal-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.
