Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522392, here are decompositions:

19 + 31522373 = 31522392
29 + 31522363 = 31522392
53 + 31522339 = 31522392
61 + 31522331 = 31522392
79 + 31522313 = 31522392
149 + 31522243 = 31522392
151 + 31522241 = 31522392
163 + 31522229 = 31522392

Showing the first eight; more decompositions exist.
