Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626104, here are decompositions:

  • 31 + 31626073 = 31626104
  • 151 + 31625953 = 31626104
  • 193 + 31625911 = 31626104
  • 283 + 31625821 = 31626104
  • 331 + 31625773 = 31626104
  • 337 + 31625767 = 31626104
  • 373 + 31625731 = 31626104
  • 457 + 31625647 = 31626104

Showing the first eight; more decompositions exist.
