Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616960, here are decompositions:

  • 31 + 31616929 = 31616960
  • 43 + 31616917 = 31616960
  • 73 + 31616887 = 31616960
  • 103 + 31616857 = 31616960
  • 211 + 31616749 = 31616960
  • 283 + 31616677 = 31616960
  • 313 + 31616647 = 31616960
  • 337 + 31616623 = 31616960

Showing the first eight; more decompositions exist.
