Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494794, here are decompositions:

13 + 31494781 = 31494794
31 + 31494763 = 31494794
73 + 31494721 = 31494794
103 + 31494691 = 31494794
151 + 31494643 = 31494794
157 + 31494637 = 31494794
211 + 31494583 = 31494794
241 + 31494553 = 31494794

Showing the first eight; more decompositions exist.
