Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544828, here are decompositions:

  • 79 + 31544749 = 31544828
  • 109 + 31544719 = 31544828
  • 241 + 31544587 = 31544828
  • 277 + 31544551 = 31544828
  • 457 + 31544371 = 31544828
  • 547 + 31544281 = 31544828
  • 607 + 31544221 = 31544828
  • 661 + 31544167 = 31544828

Showing the first eight; more decompositions exist.
