Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544838, here are decompositions:

  • 11 + 31544827 = 31544838
  • 19 + 31544819 = 31544838
  • 67 + 31544771 = 31544838
  • 79 + 31544759 = 31544838
  • 89 + 31544749 = 31544838
  • 181 + 31544657 = 31544838
  • 251 + 31544587 = 31544838
  • 277 + 31544561 = 31544838

Showing the first eight; more decompositions exist.
