Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550368, here are decompositions:

11 + 31550357 = 31550368
29 + 31550339 = 31550368
41 + 31550327 = 31550368
167 + 31550201 = 31550368
191 + 31550177 = 31550368
257 + 31550111 = 31550368
347 + 31550021 = 31550368
389 + 31549979 = 31550368

Showing the first eight; more decompositions exist.
