Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620542, here are decompositions:

  • 13 + 8620529 = 8620542
  • 43 + 8620499 = 8620542
  • 113 + 8620429 = 8620542
  • 149 + 8620393 = 8620542
  • 173 + 8620369 = 8620542
  • 181 + 8620361 = 8620542
  • 193 + 8620349 = 8620542
  • 283 + 8620259 = 8620542

Showing the first eight; more decompositions exist.
