Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645264, here are decompositions:

  • 3 + 8645261 = 8645264
  • 7 + 8645257 = 8645264
  • 151 + 8645113 = 8645264
  • 193 + 8645071 = 8645264
  • 211 + 8645053 = 8645264
  • 241 + 8645023 = 8645264
  • 307 + 8644957 = 8645264
  • 337 + 8644927 = 8645264

Showing the first eight; more decompositions exist.
