Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550360, here are decompositions:

3 + 31550357 = 31550360
7 + 31550353 = 31550360
31 + 31550329 = 31550360
73 + 31550287 = 31550360
103 + 31550257 = 31550360
109 + 31550251 = 31550360
139 + 31550221 = 31550360
181 + 31550179 = 31550360

Showing the first eight; more decompositions exist.
