Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483140, here are decompositions:

23 + 31483117 = 31483140
43 + 31483097 = 31483140
47 + 31483093 = 31483140
53 + 31483087 = 31483140
71 + 31483069 = 31483140
79 + 31483061 = 31483140
89 + 31483051 = 31483140
137 + 31483003 = 31483140

Showing the first eight; more decompositions exist.
