Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483782, here are decompositions:

23 + 31483759 = 31483782
59 + 31483723 = 31483782
199 + 31483583 = 31483782
229 + 31483553 = 31483782
233 + 31483549 = 31483782
311 + 31483471 = 31483782
313 + 31483469 = 31483782
349 + 31483433 = 31483782

Showing the first eight; more decompositions exist.
