Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527746, here are decompositions:

  • 37 + 31527709 = 31527746
  • 43 + 31527703 = 31527746
  • 163 + 31527583 = 31527746
  • 223 + 31527523 = 31527746
  • 499 + 31527247 = 31527746
  • 853 + 31526893 = 31527746
  • 883 + 31526863 = 31527746
  • 937 + 31526809 = 31527746

Showing the first eight; more decompositions exist.
