Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552548, here are decompositions:

11 + 31552537 = 31552548
59 + 31552489 = 31552548
61 + 31552487 = 31552548
127 + 31552421 = 31552548
197 + 31552351 = 31552548
239 + 31552309 = 31552548
277 + 31552271 = 31552548
311 + 31552237 = 31552548

Showing the first eight; more decompositions exist.
