Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645136, here are decompositions:

  • 13 + 8645123 = 8645136
  • 23 + 8645113 = 8645136
  • 83 + 8645053 = 8645136
  • 89 + 8645047 = 8645136
  • 107 + 8645029 = 8645136
  • 113 + 8645023 = 8645136
  • 127 + 8645009 = 8645136
  • 173 + 8644963 = 8645136

Showing the first eight; more decompositions exist.
