Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483488, here are decompositions:

17 + 31483471 = 31483488
19 + 31483469 = 31483488
31 + 31483457 = 31483488
41 + 31483447 = 31483488
59 + 31483429 = 31483488
97 + 31483391 = 31483488
137 + 31483351 = 31483488
181 + 31483307 = 31483488

Showing the first eight; more decompositions exist.
