Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494804, here are decompositions:

23 + 31494781 = 31494804
37 + 31494767 = 31494804
41 + 31494763 = 31494804
67 + 31494737 = 31494804
83 + 31494721 = 31494804
97 + 31494707 = 31494804
113 + 31494691 = 31494804
167 + 31494637 = 31494804

Showing the first eight; more decompositions exist.
