Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487026, here are decompositions:

5 + 31487021 = 31487026
59 + 31486967 = 31487026
167 + 31486859 = 31487026
173 + 31486853 = 31487026
257 + 31486769 = 31487026
293 + 31486733 = 31487026
317 + 31486709 = 31487026
383 + 31486643 = 31487026

Showing the first eight; more decompositions exist.
