Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481896, here are decompositions:

29 + 31481867 = 31481896
53 + 31481843 = 31481896
59 + 31481837 = 31481896
179 + 31481717 = 31481896
353 + 31481543 = 31481896
389 + 31481507 = 31481896
419 + 31481477 = 31481896
443 + 31481453 = 31481896

Showing the first eight; more decompositions exist.
