Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629886, here are decompositions:

3 + 8629883 = 8629886
19 + 8629867 = 8629886
73 + 8629813 = 8629886
379 + 8629507 = 8629886
439 + 8629447 = 8629886
457 + 8629429 = 8629886
607 + 8629279 = 8629886
673 + 8629213 = 8629886

Showing the first eight; more decompositions exist.
