Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483074, here are decompositions:

5 + 31483069 = 31483074
13 + 31483061 = 31483074
23 + 31483051 = 31483074
71 + 31483003 = 31483074
83 + 31482991 = 31483074
97 + 31482977 = 31483074
101 + 31482973 = 31483074
127 + 31482947 = 31483074

Showing the first eight; more decompositions exist.
