Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483892, here are decompositions:

3 + 31483889 = 31483892
31 + 31483861 = 31483892
73 + 31483819 = 31483892
103 + 31483789 = 31483892
229 + 31483663 = 31483892
421 + 31483471 = 31483892
439 + 31483453 = 31483892
463 + 31483429 = 31483892

Showing the first eight; more decompositions exist.
