Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486552, here are decompositions:

3 + 31486549 = 31486552
23 + 31486529 = 31486552
59 + 31486493 = 31486552
89 + 31486463 = 31486552
101 + 31486451 = 31486552
263 + 31486289 = 31486552
269 + 31486283 = 31486552
281 + 31486271 = 31486552

Showing the first eight; more decompositions exist.
