Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637132, here are decompositions:

  • 13 + 8637119 = 8637132
  • 29 + 8637103 = 8637132
  • 41 + 8637091 = 8637132
  • 71 + 8637061 = 8637132
  • 73 + 8637059 = 8637132
  • 79 + 8637053 = 8637132
  • 173 + 8636959 = 8637132
  • 211 + 8636921 = 8637132

Showing the first eight; more decompositions exist.
