Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624620, here are decompositions:

  • 3 + 8624617 = 8624620
  • 47 + 8624573 = 8624620
  • 113 + 8624507 = 8624620
  • 227 + 8624393 = 8624620
  • 293 + 8624327 = 8624620
  • 353 + 8624267 = 8624620
  • 383 + 8624237 = 8624620
  • 419 + 8624201 = 8624620

Showing the first eight; more decompositions exist.
