Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550570, here are decompositions:

13 + 31550557 = 31550570
31 + 31550539 = 31550570
61 + 31550509 = 31550570
109 + 31550461 = 31550570
199 + 31550371 = 31550570
241 + 31550329 = 31550570
283 + 31550287 = 31550570
313 + 31550257 = 31550570

Showing the first eight; more decompositions exist.
