Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979628, here are decompositions:

61 + 979567 = 979628
79 + 979549 = 979628
109 + 979519 = 979628
157 + 979471 = 979628
337 + 979291 = 979628
367 + 979261 = 979628
409 + 979219 = 979628
421 + 979207 = 979628

Showing the first eight; more decompositions exist.
