Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550352, here are decompositions:

13 + 31550339 = 31550352
23 + 31550329 = 31550352
101 + 31550251 = 31550352
131 + 31550221 = 31550352
139 + 31550213 = 31550352
151 + 31550201 = 31550352
173 + 31550179 = 31550352
199 + 31550153 = 31550352

Showing the first eight; more decompositions exist.
