Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544862, here are decompositions:

  • 5 + 31544857 = 31544862
  • 43 + 31544819 = 31544862
  • 79 + 31544783 = 31544862
  • 103 + 31544759 = 31544862
  • 113 + 31544749 = 31544862
  • 149 + 31544713 = 31544862
  • 311 + 31544551 = 31544862
  • 331 + 31544531 = 31544862

Showing the first eight; more decompositions exist.
