Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492706, here are decompositions:

43 + 31492663 = 31492706
79 + 31492627 = 31492706
103 + 31492603 = 31492706
109 + 31492597 = 31492706
139 + 31492567 = 31492706
229 + 31492477 = 31492706
277 + 31492429 = 31492706
283 + 31492423 = 31492706

Showing the first eight; more decompositions exist.
