Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 416, here are decompositions:

  • 7 + 409 = 416
  • 19 + 397 = 416
  • 37 + 379 = 416
  • 43 + 373 = 416
  • 67 + 349 = 416
  • 79 + 337 = 416
  • 103 + 313 = 416
  • 109 + 307 = 416

Showing the first eight; more decompositions exist.
