Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544020, here are decompositions:

  • 23 + 31543997 = 31544020
  • 29 + 31543991 = 31544020
  • 41 + 31543979 = 31544020
  • 59 + 31543961 = 31544020
  • 107 + 31543913 = 31544020
  • 113 + 31543907 = 31544020
  • 149 + 31543871 = 31544020
  • 173 + 31543847 = 31544020

Showing the first eight; more decompositions exist.
