Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738988, here are decompositions:

  • 31 + 8738957 = 8738988
  • 59 + 8738929 = 8738988
  • 107 + 8738881 = 8738988
  • 149 + 8738839 = 8738988
  • 151 + 8738837 = 8738988
  • 179 + 8738809 = 8738988
  • 229 + 8738759 = 8738988
  • 277 + 8738711 = 8738988

Showing the first eight; more decompositions exist.
