Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979578, here are decompositions:

11 + 979567 = 979578
29 + 979549 = 979578
37 + 979541 = 979578
59 + 979519 = 979578
97 + 979481 = 979578
107 + 979471 = 979578
139 + 979439 = 979578
199 + 979379 = 979578

Showing the first eight; more decompositions exist.
