Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66124, here are decompositions:

  • 17 + 66107 = 66124
  • 41 + 66083 = 66124
  • 53 + 66071 = 66124
  • 83 + 66041 = 66124
  • 131 + 65993 = 66124
  • 167 + 65957 = 66124
  • 173 + 65951 = 66124
  • 197 + 65927 = 66124

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66124 first appears in π at position 259,708 of the decimal expansion (the 259,708ordinal-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.
