Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629688, here are decompositions:

7 + 8629681 = 8629688
37 + 8629651 = 8629688
127 + 8629561 = 8629688
181 + 8629507 = 8629688
241 + 8629447 = 8629688
409 + 8629279 = 8629688
547 + 8629141 = 8629688
601 + 8629087 = 8629688

Showing the first eight; more decompositions exist.
