Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979458, here are decompositions:

19 + 979439 = 979458
79 + 979379 = 979458
89 + 979369 = 979458
97 + 979361 = 979458
131 + 979327 = 979458
167 + 979291 = 979458
197 + 979261 = 979458
229 + 979229 = 979458

Showing the first eight; more decompositions exist.
