Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481514, here are decompositions:

5 + 31481509 = 31481514
7 + 31481507 = 31481514
17 + 31481497 = 31481514
37 + 31481477 = 31481514
41 + 31481473 = 31481514
61 + 31481453 = 31481514
83 + 31481431 = 31481514
107 + 31481407 = 31481514

Showing the first eight; more decompositions exist.
