Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550852, here are decompositions:

19 + 31550833 = 31550852
61 + 31550791 = 31550852
181 + 31550671 = 31550852
241 + 31550611 = 31550852
271 + 31550581 = 31550852
283 + 31550569 = 31550852
313 + 31550539 = 31550852
373 + 31550479 = 31550852

Showing the first eight; more decompositions exist.
