Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522494, here are decompositions:

43 + 31522451 = 31522494
53 + 31522441 = 31522494
61 + 31522433 = 31522494
83 + 31522411 = 31522494
131 + 31522363 = 31522494
137 + 31522357 = 31522494
163 + 31522331 = 31522494
167 + 31522327 = 31522494

Showing the first eight; more decompositions exist.
