Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494974, here are decompositions:

31 + 31494943 = 31494974
37 + 31494937 = 31494974
67 + 31494907 = 31494974
157 + 31494817 = 31494974
193 + 31494781 = 31494974
211 + 31494763 = 31494974
283 + 31494691 = 31494974
331 + 31494643 = 31494974

Showing the first eight; more decompositions exist.
