Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552566, here are decompositions:

13 + 31552553 = 31552566
29 + 31552537 = 31552566
79 + 31552487 = 31552566
137 + 31552429 = 31552566
163 + 31552403 = 31552566
173 + 31552393 = 31552566
179 + 31552387 = 31552566
257 + 31552309 = 31552566

Showing the first eight; more decompositions exist.
