Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552644, here are decompositions:

5 + 31552639 = 31552644
23 + 31552621 = 31552644
41 + 31552603 = 31552644
107 + 31552537 = 31552644
157 + 31552487 = 31552644
223 + 31552421 = 31552644
241 + 31552403 = 31552644
251 + 31552393 = 31552644

Showing the first eight; more decompositions exist.
