Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550588, here are decompositions:

7 + 31550581 = 31550588
19 + 31550569 = 31550588
31 + 31550557 = 31550588
79 + 31550509 = 31550588
109 + 31550479 = 31550588
127 + 31550461 = 31550588
151 + 31550437 = 31550588
331 + 31550257 = 31550588

Showing the first eight; more decompositions exist.
