Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979540, here are decompositions:

11 + 979529 = 979540
59 + 979481 = 979540
83 + 979457 = 979540
101 + 979439 = 979540
137 + 979403 = 979540
167 + 979373 = 979540
179 + 979361 = 979540
197 + 979343 = 979540

Showing the first eight; more decompositions exist.
