Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483494, here are decompositions:

23 + 31483471 = 31483494
37 + 31483457 = 31483494
41 + 31483453 = 31483494
47 + 31483447 = 31483494
61 + 31483433 = 31483494
103 + 31483391 = 31483494
167 + 31483327 = 31483494
181 + 31483313 = 31483494

Showing the first eight; more decompositions exist.
