Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532748, here are decompositions:

11 + 31532737 = 31532748
61 + 31532687 = 31532748
89 + 31532659 = 31532748
109 + 31532639 = 31532748
151 + 31532597 = 31532748
167 + 31532581 = 31532748
197 + 31532551 = 31532748
227 + 31532521 = 31532748

Showing the first eight; more decompositions exist.
