Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527522, here are decompositions:

23 + 31527499 = 31527522
31 + 31527491 = 31527522
41 + 31527481 = 31527522
109 + 31527413 = 31527522
179 + 31527343 = 31527522
199 + 31527323 = 31527522
211 + 31527311 = 31527522
269 + 31527253 = 31527522

Showing the first eight; more decompositions exist.
