Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522692, here are decompositions:

23 + 31522669 = 31522692
29 + 31522663 = 31522692
59 + 31522633 = 31522692
79 + 31522613 = 31522692
101 + 31522591 = 31522692
109 + 31522583 = 31522692
139 + 31522553 = 31522692
151 + 31522541 = 31522692

Showing the first eight; more decompositions exist.
