Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508578, here are decompositions:

11 + 508567 = 508578
19 + 508559 = 508578
29 + 508549 = 508578
47 + 508531 = 508578
61 + 508517 = 508578
79 + 508499 = 508578
89 + 508489 = 508578
101 + 508477 = 508578

Showing the first eight; more decompositions exist.
