Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483466, here are decompositions:

13 + 31483453 = 31483466
19 + 31483447 = 31483466
37 + 31483429 = 31483466
97 + 31483369 = 31483466
139 + 31483327 = 31483466
229 + 31483237 = 31483466
349 + 31483117 = 31483466
373 + 31483093 = 31483466

Showing the first eight; more decompositions exist.
