Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628028, here are decompositions:

  • 11 + 8628017 = 8628028
  • 41 + 8627987 = 8628028
  • 89 + 8627939 = 8628028
  • 131 + 8627897 = 8628028
  • 251 + 8627777 = 8628028
  • 347 + 8627681 = 8628028
  • 389 + 8627639 = 8628028
  • 401 + 8627627 = 8628028

Showing the first eight; more decompositions exist.
