Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522462, here are decompositions:

3 + 31522459 = 31522462
11 + 31522451 = 31522462
29 + 31522433 = 31522462
89 + 31522373 = 31522462
131 + 31522331 = 31522462
149 + 31522313 = 31522462
233 + 31522229 = 31522462
281 + 31522181 = 31522462

Showing the first eight; more decompositions exist.
