Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979442, here are decompositions:

3 + 979439 = 979442
19 + 979423 = 979442
73 + 979369 = 979442
109 + 979333 = 979442
151 + 979291 = 979442
181 + 979261 = 979442
223 + 979219 = 979442
241 + 979201 = 979442

Showing the first eight; more decompositions exist.
