Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483516, here are decompositions:

23 + 31483493 = 31483516
47 + 31483469 = 31483516
59 + 31483457 = 31483516
83 + 31483433 = 31483516
347 + 31483169 = 31483516
353 + 31483163 = 31483516
419 + 31483097 = 31483516
569 + 31482947 = 31483516

Showing the first eight; more decompositions exist.
