Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494962, here are decompositions:

13 + 31494949 = 31494962
19 + 31494943 = 31494962
43 + 31494919 = 31494962
181 + 31494781 = 31494962
193 + 31494769 = 31494962
199 + 31494763 = 31494962
241 + 31494721 = 31494962
271 + 31494691 = 31494962

Showing the first eight; more decompositions exist.
