Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486426, here are decompositions:

3 + 31486423 = 31486426
89 + 31486337 = 31486426
137 + 31486289 = 31486426
173 + 31486253 = 31486426
197 + 31486229 = 31486426
263 + 31486163 = 31486426
317 + 31486109 = 31486426
467 + 31485959 = 31486426

Showing the first eight; more decompositions exist.
