Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522524, here are decompositions:

31 + 31522493 = 31522524
73 + 31522451 = 31522524
83 + 31522441 = 31522524
113 + 31522411 = 31522524
151 + 31522373 = 31522524
167 + 31522357 = 31522524
193 + 31522331 = 31522524
197 + 31522327 = 31522524

Showing the first eight; more decompositions exist.
