Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622490, here are decompositions:

  • 3 + 8622487 = 8622490
  • 17 + 8622473 = 8622490
  • 29 + 8622461 = 8622490
  • 131 + 8622359 = 8622490
  • 137 + 8622353 = 8622490
  • 167 + 8622323 = 8622490
  • 197 + 8622293 = 8622490
  • 281 + 8622209 = 8622490

Showing the first eight; more decompositions exist.
