Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645150, here are decompositions:

  • 37 + 8645113 = 8645150
  • 79 + 8645071 = 8645150
  • 97 + 8645053 = 8645150
  • 103 + 8645047 = 8645150
  • 127 + 8645023 = 8645150
  • 139 + 8645011 = 8645150
  • 193 + 8644957 = 8645150
  • 223 + 8644927 = 8645150

Showing the first eight; more decompositions exist.
