Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486276, here are decompositions:

5 + 31486271 = 31486276
23 + 31486253 = 31486276
47 + 31486229 = 31486276
113 + 31486163 = 31486276
167 + 31486109 = 31486276
317 + 31485959 = 31486276
359 + 31485917 = 31486276
383 + 31485893 = 31486276

Showing the first eight; more decompositions exist.
