Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483862, here are decompositions:

43 + 31483819 = 31483862
61 + 31483801 = 31483862
73 + 31483789 = 31483862
103 + 31483759 = 31483862
139 + 31483723 = 31483862
199 + 31483663 = 31483862
313 + 31483549 = 31483862
409 + 31483453 = 31483862

Showing the first eight; more decompositions exist.
