Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522300, here are decompositions:

3 + 31522297 = 31522300
23 + 31522277 = 31522300
53 + 31522247 = 31522300
59 + 31522241 = 31522300
71 + 31522229 = 31522300
197 + 31522103 = 31522300
239 + 31522061 = 31522300
281 + 31522019 = 31522300

Showing the first eight; more decompositions exist.
