Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492614, here are decompositions:

11 + 31492603 = 31492614
17 + 31492597 = 31492614
37 + 31492577 = 31492614
47 + 31492567 = 31492614
61 + 31492553 = 31492614
73 + 31492541 = 31492614
137 + 31492477 = 31492614
191 + 31492423 = 31492614

Showing the first eight; more decompositions exist.
