Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522514, here are decompositions:

73 + 31522441 = 31522514
103 + 31522411 = 31522514
151 + 31522363 = 31522514
157 + 31522357 = 31522514
271 + 31522243 = 31522514
307 + 31522207 = 31522514
523 + 31521991 = 31522514
631 + 31521883 = 31522514

Showing the first eight; more decompositions exist.
