Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522526, here are decompositions:

3 + 31522523 = 31522526
67 + 31522459 = 31522526
163 + 31522363 = 31522526
199 + 31522327 = 31522526
229 + 31522297 = 31522526
283 + 31522243 = 31522526
307 + 31522219 = 31522526
397 + 31522129 = 31522526

Showing the first eight; more decompositions exist.
