Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627980, here are decompositions:

  • 3 + 8627977 = 8627980
  • 41 + 8627939 = 8627980
  • 71 + 8627909 = 8627980
  • 83 + 8627897 = 8627980
  • 113 + 8627867 = 8627980
  • 167 + 8627813 = 8627980
  • 173 + 8627807 = 8627980
  • 239 + 8627741 = 8627980

Showing the first eight; more decompositions exist.
