Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629946, here are decompositions:

19 + 8629927 = 8629946
37 + 8629909 = 8629946
79 + 8629867 = 8629946
349 + 8629597 = 8629946
439 + 8629507 = 8629946
463 + 8629483 = 8629946
499 + 8629447 = 8629946
613 + 8629333 = 8629946

Showing the first eight; more decompositions exist.
