Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492982, here are decompositions:

19 + 31492963 = 31492982
61 + 31492921 = 31492982
181 + 31492801 = 31492982
211 + 31492771 = 31492982
331 + 31492651 = 31492982
379 + 31492603 = 31492982
613 + 31492369 = 31492982
739 + 31492243 = 31492982

Showing the first eight; more decompositions exist.
