Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481466, here are decompositions:

7 + 31481459 = 31481466
13 + 31481453 = 31481466
17 + 31481449 = 31481466
47 + 31481419 = 31481466
59 + 31481407 = 31481466
73 + 31481393 = 31481466
83 + 31481383 = 31481466
97 + 31481369 = 31481466

Showing the first eight; more decompositions exist.
