Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522232, here are decompositions:

3 + 31522229 = 31522232
13 + 31522219 = 31522232
103 + 31522129 = 31522232
211 + 31522021 = 31522232
241 + 31521991 = 31522232
349 + 31521883 = 31522232
439 + 31521793 = 31522232
661 + 31521571 = 31522232

Showing the first eight; more decompositions exist.
