Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628558, here are decompositions:

  • 5 + 8628553 = 8628558
  • 7 + 8628551 = 8628558
  • 11 + 8628547 = 8628558
  • 79 + 8628479 = 8628558
  • 109 + 8628449 = 8628558
  • 137 + 8628421 = 8628558
  • 151 + 8628407 = 8628558
  • 181 + 8628377 = 8628558

Showing the first eight; more decompositions exist.
