Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483682, here are decompositions:

19 + 31483663 = 31483682
211 + 31483471 = 31483682
229 + 31483453 = 31483682
313 + 31483369 = 31483682
331 + 31483351 = 31483682
421 + 31483261 = 31483682
613 + 31483069 = 31483682
631 + 31483051 = 31483682

Showing the first eight; more decompositions exist.
