Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522576, here are decompositions:

23 + 31522553 = 31522576
47 + 31522529 = 31522576
53 + 31522523 = 31522576
83 + 31522493 = 31522576
263 + 31522313 = 31522576
347 + 31522229 = 31522576
557 + 31522019 = 31522576
563 + 31522013 = 31522576

Showing the first eight; more decompositions exist.
