Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478826, here are decompositions:

3 + 478823 = 478826
13 + 478813 = 478826
79 + 478747 = 478826
97 + 478729 = 478826
199 + 478627 = 478826
223 + 478603 = 478826
367 + 478459 = 478826
373 + 478453 = 478826

Showing the first eight; more decompositions exist.
