Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522516, here are decompositions:

23 + 31522493 = 31522516
83 + 31522433 = 31522516
239 + 31522277 = 31522516
269 + 31522247 = 31522516
503 + 31522013 = 31522516
563 + 31521953 = 31522516
653 + 31521863 = 31522516
1049 + 31521467 = 31522516

Showing the first eight; more decompositions exist.
