Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 979888, here are decompositions:

5 + 979883 = 979888
101 + 979787 = 979888
131 + 979757 = 979888
179 + 979709 = 979888
197 + 979691 = 979888
347 + 979541 = 979888
359 + 979529 = 979888
431 + 979457 = 979888

Showing the first eight; more decompositions exist.
