Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629826, here are decompositions:

3 + 8629823 = 8629826
13 + 8629813 = 8629826
229 + 8629597 = 8629826
379 + 8629447 = 8629826
397 + 8629429 = 8629826
547 + 8629279 = 8629826
613 + 8629213 = 8629826
739 + 8629087 = 8629826

Showing the first eight; more decompositions exist.
