Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481464, here are decompositions:

5 + 31481459 = 31481464
11 + 31481453 = 31481464
71 + 31481393 = 31481464
227 + 31481237 = 31481464
233 + 31481231 = 31481464
257 + 31481207 = 31481464
263 + 31481201 = 31481464
293 + 31481171 = 31481464

Showing the first eight; more decompositions exist.
