Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522562, here are decompositions:

13 + 31522549 = 31522562
103 + 31522459 = 31522562
151 + 31522411 = 31522562
199 + 31522363 = 31522562
223 + 31522339 = 31522562
433 + 31522129 = 31522562
541 + 31522021 = 31522562
571 + 31521991 = 31522562

Showing the first eight; more decompositions exist.
