Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552492, here are decompositions:

3 + 31552489 = 31552492
5 + 31552487 = 31552492
71 + 31552421 = 31552492
89 + 31552403 = 31552492
239 + 31552253 = 31552492
263 + 31552229 = 31552492
281 + 31552211 = 31552492
353 + 31552139 = 31552492

Showing the first eight; more decompositions exist.
