Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979486, here are decompositions:

5 + 979481 = 979486
29 + 979457 = 979486
47 + 979439 = 979486
83 + 979403 = 979486
107 + 979379 = 979486
113 + 979373 = 979486
149 + 979337 = 979486
173 + 979313 = 979486

Showing the first eight; more decompositions exist.
