Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617230, here are decompositions:

  • 31 + 31617199 = 31617230
  • 97 + 31617133 = 31617230
  • 157 + 31617073 = 31617230
  • 181 + 31617049 = 31617230
  • 313 + 31616917 = 31617230
  • 373 + 31616857 = 31617230
  • 457 + 31616773 = 31617230
  • 523 + 31616707 = 31617230

Showing the first eight; more decompositions exist.
