Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629228, here are decompositions:

29 + 8629199 = 8629228
59 + 8629169 = 8629228
71 + 8629157 = 8629228
89 + 8629139 = 8629228
149 + 8629079 = 8629228
449 + 8628779 = 8629228
599 + 8628629 = 8629228
677 + 8628551 = 8629228

Showing the first eight; more decompositions exist.
