Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552222, here are decompositions:

11 + 31552211 = 31552222
29 + 31552193 = 31552222
83 + 31552139 = 31552222
173 + 31552049 = 31552222
263 + 31551959 = 31552222
281 + 31551941 = 31552222
419 + 31551803 = 31552222
593 + 31551629 = 31552222

Showing the first eight; more decompositions exist.
