Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574094, here are decompositions:

23 + 31574071 = 31574094
47 + 31574047 = 31574094
53 + 31574041 = 31574094
73 + 31574021 = 31574094
127 + 31573967 = 31574094
137 + 31573957 = 31574094
163 + 31573931 = 31574094
241 + 31573853 = 31574094

Showing the first eight; more decompositions exist.
