Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522992, here are decompositions:

5 + 31522987 = 31522992
13 + 31522979 = 31522992
31 + 31522961 = 31522992
41 + 31522951 = 31522992
103 + 31522889 = 31522992
359 + 31522633 = 31522992
379 + 31522613 = 31522992
401 + 31522591 = 31522992

Showing the first eight; more decompositions exist.
