Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550774, here are decompositions:

  • 43 + 31550731 = 31550774
  • 103 + 31550671 = 31550774
  • 163 + 31550611 = 31550774
  • 181 + 31550593 = 31550774
  • 193 + 31550581 = 31550774
  • 313 + 31550461 = 31550774
  • 337 + 31550437 = 31550774
  • 373 + 31550401 = 31550774

Showing the first eight; more decompositions exist.
