Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494000, here are decompositions:

11 + 31493989 = 31494000
17 + 31493983 = 31494000
59 + 31493941 = 31494000
73 + 31493927 = 31494000
101 + 31493899 = 31494000
149 + 31493851 = 31494000
179 + 31493821 = 31494000
211 + 31493789 = 31494000

Showing the first eight; more decompositions exist.
