Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629940, here are decompositions:

13 + 8629927 = 8629940
31 + 8629909 = 8629940
73 + 8629867 = 8629940
127 + 8629813 = 8629940
229 + 8629711 = 8629940
379 + 8629561 = 8629940
433 + 8629507 = 8629940
457 + 8629483 = 8629940

Showing the first eight; more decompositions exist.
