Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544792, here are decompositions:

  • 43 + 31544749 = 31544792
  • 73 + 31544719 = 31544792
  • 79 + 31544713 = 31544792
  • 241 + 31544551 = 31544792
  • 283 + 31544509 = 31544792
  • 421 + 31544371 = 31544792
  • 571 + 31544221 = 31544792
  • 613 + 31544179 = 31544792

Showing the first eight; more decompositions exist.
