Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483500, here are decompositions:

7 + 31483493 = 31483500
29 + 31483471 = 31483500
31 + 31483469 = 31483500
43 + 31483457 = 31483500
47 + 31483453 = 31483500
53 + 31483447 = 31483500
67 + 31483433 = 31483500
71 + 31483429 = 31483500

Showing the first eight; more decompositions exist.
