Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483154, here are decompositions:

37 + 31483117 = 31483154
61 + 31483093 = 31483154
67 + 31483087 = 31483154
103 + 31483051 = 31483154
151 + 31483003 = 31483154
163 + 31482991 = 31483154
181 + 31482973 = 31483154
331 + 31482823 = 31483154

Showing the first eight; more decompositions exist.
