Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544462, here are decompositions:

  • 139 + 31544323 = 31544462
  • 151 + 31544311 = 31544462
  • 181 + 31544281 = 31544462
  • 241 + 31544221 = 31544462
  • 283 + 31544179 = 31544462
  • 331 + 31544131 = 31544462
  • 373 + 31544089 = 31544462
  • 409 + 31544053 = 31544462

Showing the first eight; more decompositions exist.
