Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617000, here are decompositions:

  • 13 + 31616987 = 31617000
  • 67 + 31616933 = 31617000
  • 71 + 31616929 = 31617000
  • 83 + 31616917 = 31617000
  • 97 + 31616903 = 31617000
  • 109 + 31616891 = 31617000
  • 113 + 31616887 = 31617000
  • 227 + 31616773 = 31617000

Showing the first eight; more decompositions exist.
