Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552228, here are decompositions:

17 + 31552211 = 31552228
89 + 31552139 = 31552228
101 + 31552127 = 31552228
179 + 31552049 = 31552228
251 + 31551977 = 31552228
269 + 31551959 = 31552228
401 + 31551827 = 31552228
557 + 31551671 = 31552228

Showing the first eight; more decompositions exist.
