Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481534, here are decompositions:

3 + 31481531 = 31481534
13 + 31481521 = 31481534
37 + 31481497 = 31481534
61 + 31481473 = 31481534
103 + 31481431 = 31481534
127 + 31481407 = 31481534
151 + 31481383 = 31481534
163 + 31481371 = 31481534

Showing the first eight; more decompositions exist.
