Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481496, here are decompositions:

17 + 31481479 = 31481496
19 + 31481477 = 31481496
23 + 31481473 = 31481496
37 + 31481459 = 31481496
43 + 31481453 = 31481496
47 + 31481449 = 31481496
89 + 31481407 = 31481496
103 + 31481393 = 31481496

Showing the first eight; more decompositions exist.
