Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522484, here are decompositions:

43 + 31522441 = 31522484
73 + 31522411 = 31522484
127 + 31522357 = 31522484
157 + 31522327 = 31522484
241 + 31522243 = 31522484
277 + 31522207 = 31522484
463 + 31522021 = 31522484
601 + 31521883 = 31522484

Showing the first eight; more decompositions exist.
