Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611522, here are decompositions:

13 + 31611509 = 31611522
83 + 31611439 = 31611522
181 + 31611341 = 31611522
193 + 31611329 = 31611522
199 + 31611323 = 31611522
211 + 31611311 = 31611522
223 + 31611299 = 31611522
251 + 31611271 = 31611522

Showing the first eight; more decompositions exist.
