Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550496, here are decompositions:

17 + 31550479 = 31550496
37 + 31550459 = 31550496
59 + 31550437 = 31550496
139 + 31550357 = 31550496
157 + 31550339 = 31550496
167 + 31550329 = 31550496
239 + 31550257 = 31550496
283 + 31550213 = 31550496

Showing the first eight; more decompositions exist.
