Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647258, here are decompositions:

  • 5 + 8647253 = 8647258
  • 29 + 8647229 = 8647258
  • 101 + 8647157 = 8647258
  • 131 + 8647127 = 8647258
  • 167 + 8647091 = 8647258
  • 197 + 8647061 = 8647258
  • 227 + 8647031 = 8647258
  • 251 + 8647007 = 8647258

Showing the first eight; more decompositions exist.
