Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552056, here are decompositions:

7 + 31552049 = 31552056
23 + 31552033 = 31552056
37 + 31552019 = 31552056
59 + 31551997 = 31552056
79 + 31551977 = 31552056
97 + 31551959 = 31552056
197 + 31551859 = 31552056
199 + 31551857 = 31552056

Showing the first eight; more decompositions exist.
