Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738940, here are decompositions:

  • 11 + 8738929 = 8738940
  • 59 + 8738881 = 8738940
  • 97 + 8738843 = 8738940
  • 101 + 8738839 = 8738940
  • 103 + 8738837 = 8738940
  • 127 + 8738813 = 8738940
  • 131 + 8738809 = 8738940
  • 139 + 8738801 = 8738940

Showing the first eight; more decompositions exist.
