Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647618, here are decompositions:

  • 29 + 8647589 = 8647618
  • 107 + 8647511 = 8647618
  • 149 + 8647469 = 8647618
  • 227 + 8647391 = 8647618
  • 251 + 8647367 = 8647618
  • 269 + 8647349 = 8647618
  • 389 + 8647229 = 8647618
  • 461 + 8647157 = 8647618

Showing the first eight; more decompositions exist.
