Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493494, here are decompositions:

17 + 31493477 = 31493494
47 + 31493447 = 31493494
173 + 31493321 = 31493494
293 + 31493201 = 31493494
503 + 31492991 = 31493494
587 + 31492907 = 31493494
647 + 31492847 = 31493494
653 + 31492841 = 31493494

Showing the first eight; more decompositions exist.
