Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625740, here are decompositions:

  • 7 + 8625733 = 8625740
  • 31 + 8625709 = 8625740
  • 103 + 8625637 = 8625740
  • 181 + 8625559 = 8625740
  • 199 + 8625541 = 8625740
  • 223 + 8625517 = 8625740
  • 397 + 8625343 = 8625740
  • 439 + 8625301 = 8625740

Showing the first eight; more decompositions exist.
