Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979720, here are decompositions:

3 + 979717 = 979720
11 + 979709 = 979720
29 + 979691 = 979720
167 + 979553 = 979720
179 + 979541 = 979720
191 + 979529 = 979720
239 + 979481 = 979720
263 + 979457 = 979720

Showing the first eight; more decompositions exist.
