Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552252, here are decompositions:

23 + 31552229 = 31552252
41 + 31552211 = 31552252
59 + 31552193 = 31552252
113 + 31552139 = 31552252
233 + 31552019 = 31552252
293 + 31551959 = 31552252
311 + 31551941 = 31552252
449 + 31551803 = 31552252

Showing the first eight; more decompositions exist.
