Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492670, here are decompositions:

3 + 31492667 = 31492670
7 + 31492663 = 31492670
19 + 31492651 = 31492670
43 + 31492627 = 31492670
67 + 31492603 = 31492670
73 + 31492597 = 31492670
103 + 31492567 = 31492670
193 + 31492477 = 31492670

Showing the first eight; more decompositions exist.
