Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552896, here are decompositions:

5 + 31552891 = 31552896
13 + 31552883 = 31552896
17 + 31552879 = 31552896
43 + 31552853 = 31552896
79 + 31552817 = 31552896
149 + 31552747 = 31552896
163 + 31552733 = 31552896
257 + 31552639 = 31552896

Showing the first eight; more decompositions exist.
