Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552312, here are decompositions:

3 + 31552309 = 31552312
41 + 31552271 = 31552312
59 + 31552253 = 31552312
83 + 31552229 = 31552312
101 + 31552211 = 31552312
173 + 31552139 = 31552312
263 + 31552049 = 31552312
293 + 31552019 = 31552312

Showing the first eight; more decompositions exist.
