Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552506, here are decompositions:

17 + 31552489 = 31552506
19 + 31552487 = 31552506
103 + 31552403 = 31552506
113 + 31552393 = 31552506
197 + 31552309 = 31552506
269 + 31552237 = 31552506
277 + 31552229 = 31552506
313 + 31552193 = 31552506

Showing the first eight; more decompositions exist.
