Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486522, here are decompositions:

29 + 31486493 = 31486522
59 + 31486463 = 31486522
71 + 31486451 = 31486522
131 + 31486391 = 31486522
173 + 31486349 = 31486522
233 + 31486289 = 31486522
239 + 31486283 = 31486522
251 + 31486271 = 31486522

Showing the first eight; more decompositions exist.
