Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494660, here are decompositions:

17 + 31494643 = 31494660
23 + 31494637 = 31494660
79 + 31494581 = 31494660
107 + 31494553 = 31494660
151 + 31494509 = 31494660
157 + 31494503 = 31494660
163 + 31494497 = 31494660
181 + 31494479 = 31494660

Showing the first eight; more decompositions exist.
