Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481596, here are decompositions:

5 + 31481591 = 31481596
53 + 31481543 = 31481596
89 + 31481507 = 31481596
137 + 31481459 = 31481596
227 + 31481369 = 31481596
347 + 31481249 = 31481596
359 + 31481237 = 31481596
389 + 31481207 = 31481596

Showing the first eight; more decompositions exist.
