Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494774, here are decompositions:

5 + 31494769 = 31494774
7 + 31494767 = 31494774
11 + 31494763 = 31494774
37 + 31494737 = 31494774
53 + 31494721 = 31494774
61 + 31494713 = 31494774
67 + 31494707 = 31494774
83 + 31494691 = 31494774

Showing the first eight; more decompositions exist.
