Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483260, here are decompositions:

23 + 31483237 = 31483260
31 + 31483229 = 31483260
43 + 31483217 = 31483260
47 + 31483213 = 31483260
97 + 31483163 = 31483260
163 + 31483097 = 31483260
167 + 31483093 = 31483260
173 + 31483087 = 31483260

Showing the first eight; more decompositions exist.
