Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481526, here are decompositions:

5 + 31481521 = 31481526
17 + 31481509 = 31481526
19 + 31481507 = 31481526
29 + 31481497 = 31481526
47 + 31481479 = 31481526
53 + 31481473 = 31481526
67 + 31481459 = 31481526
73 + 31481453 = 31481526

Showing the first eight; more decompositions exist.
