Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545364, here are decompositions:

  • 41 + 31545323 = 31545364
  • 47 + 31545317 = 31545364
  • 131 + 31545233 = 31545364
  • 173 + 31545191 = 31545364
  • 281 + 31545083 = 31545364
  • 401 + 31544963 = 31545364
  • 593 + 31544771 = 31545364
  • 647 + 31544717 = 31545364

Showing the first eight; more decompositions exist.
