Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483128, here are decompositions:

11 + 31483117 = 31483128
31 + 31483097 = 31483128
41 + 31483087 = 31483128
59 + 31483069 = 31483128
67 + 31483061 = 31483128
137 + 31482991 = 31483128
151 + 31482977 = 31483128
181 + 31482947 = 31483128

Showing the first eight; more decompositions exist.
