Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613388, here are decompositions:

  • 41 + 8613347 = 8613388
  • 59 + 8613329 = 8613388
  • 89 + 8613299 = 8613388
  • 107 + 8613281 = 8613388
  • 167 + 8613221 = 8613388
  • 227 + 8613161 = 8613388
  • 239 + 8613149 = 8613388
  • 281 + 8613107 = 8613388

Showing the first eight; more decompositions exist.
