Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486366, here are decompositions:

17 + 31486349 = 31486366
29 + 31486337 = 31486366
59 + 31486307 = 31486366
83 + 31486283 = 31486366
113 + 31486253 = 31486366
137 + 31486229 = 31486366
257 + 31486109 = 31486366
449 + 31485917 = 31486366

Showing the first eight; more decompositions exist.
