Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979402, here are decompositions:

23 + 979379 = 979402
29 + 979373 = 979402
41 + 979361 = 979402
59 + 979343 = 979402
89 + 979313 = 979402
173 + 979229 = 979402
191 + 979211 = 979402
239 + 979163 = 979402

Showing the first eight; more decompositions exist.
