Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552484, here are decompositions:

97 + 31552387 = 31552484
181 + 31552303 = 31552484
277 + 31552207 = 31552484
487 + 31551997 = 31552484
547 + 31551937 = 31552484
631 + 31551853 = 31552484
727 + 31551757 = 31552484
751 + 31551733 = 31552484

Showing the first eight; more decompositions exist.
