Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721062, here are decompositions:

  • 13 + 8721049 = 8721062
  • 19 + 8721043 = 8721062
  • 109 + 8720953 = 8721062
  • 151 + 8720911 = 8721062
  • 223 + 8720839 = 8721062
  • 349 + 8720713 = 8721062
  • 373 + 8720689 = 8721062
  • 433 + 8720629 = 8721062

Showing the first eight; more decompositions exist.
