Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620538, here are decompositions:

  • 109 + 8620429 = 8620538
  • 211 + 8620327 = 8620538
  • 271 + 8620267 = 8620538
  • 307 + 8620231 = 8620538
  • 349 + 8620189 = 8620538
  • 379 + 8620159 = 8620538
  • 397 + 8620141 = 8620538
  • 541 + 8619997 = 8620538

Showing the first eight; more decompositions exist.
