Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544178, here are decompositions:

  • 7 + 31544171 = 31544178
  • 11 + 31544167 = 31544178
  • 47 + 31544131 = 31544178
  • 79 + 31544099 = 31544178
  • 89 + 31544089 = 31544178
  • 101 + 31544077 = 31544178
  • 137 + 31544041 = 31544178
  • 139 + 31544039 = 31544178

Showing the first eight; more decompositions exist.
