Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483540, here are decompositions:

47 + 31483493 = 31483540
71 + 31483469 = 31483540
83 + 31483457 = 31483540
107 + 31483433 = 31483540
149 + 31483391 = 31483540
227 + 31483313 = 31483540
233 + 31483307 = 31483540
311 + 31483229 = 31483540

Showing the first eight; more decompositions exist.
