Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637340, here are decompositions:

  • 3 + 8637337 = 8637340
  • 17 + 8637323 = 8637340
  • 29 + 8637311 = 8637340
  • 83 + 8637257 = 8637340
  • 113 + 8637227 = 8637340
  • 137 + 8637203 = 8637340
  • 233 + 8637107 = 8637340
  • 281 + 8637059 = 8637340

Showing the first eight; more decompositions exist.
