Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550744, here are decompositions:

13 + 31550731 = 31550744
73 + 31550671 = 31550744
151 + 31550593 = 31550744
157 + 31550587 = 31550744
163 + 31550581 = 31550744
283 + 31550461 = 31550744
307 + 31550437 = 31550744
373 + 31550371 = 31550744

Showing the first eight; more decompositions exist.
