Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522406, here are decompositions:

43 + 31522363 = 31522406
67 + 31522339 = 31522406
79 + 31522327 = 31522406
109 + 31522297 = 31522406
163 + 31522243 = 31522406
199 + 31522207 = 31522406
277 + 31522129 = 31522406
523 + 31521883 = 31522406

Showing the first eight; more decompositions exist.
