Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489466, here are decompositions:

3 + 31489463 = 31489466
67 + 31489399 = 31489466
103 + 31489363 = 31489466
223 + 31489243 = 31489466
397 + 31489069 = 31489466
439 + 31489027 = 31489466
457 + 31489009 = 31489466
487 + 31488979 = 31489466

Showing the first eight; more decompositions exist.
