Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7208, here are decompositions:

  • 31 + 7177 = 7208
  • 79 + 7129 = 7208
  • 139 + 7069 = 7208
  • 151 + 7057 = 7208
  • 181 + 7027 = 7208
  • 211 + 6997 = 7208
  • 241 + 6967 = 7208
  • 337 + 6871 = 7208

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7208 first appears in π at position 26,314 of the decimal expansion (the 26,314ordinal-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.
