Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522474, here are decompositions:

23 + 31522451 = 31522474
41 + 31522433 = 31522474
101 + 31522373 = 31522474
197 + 31522277 = 31522474
227 + 31522247 = 31522474
233 + 31522241 = 31522474
293 + 31522181 = 31522474
383 + 31522091 = 31522474

Showing the first eight; more decompositions exist.
