Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544206, here are decompositions:

  • 17 + 31544189 = 31544206
  • 53 + 31544153 = 31544206
  • 107 + 31544099 = 31544206
  • 149 + 31544057 = 31544206
  • 167 + 31544039 = 31544206
  • 173 + 31544033 = 31544206
  • 227 + 31543979 = 31544206
  • 293 + 31543913 = 31544206

Showing the first eight; more decompositions exist.
