Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486092, here are decompositions:

5 + 31486087 = 31486092
59 + 31486033 = 31486092
83 + 31486009 = 31486092
139 + 31485953 = 31486092
151 + 31485941 = 31486092
199 + 31485893 = 31486092
269 + 31485823 = 31486092
293 + 31485799 = 31486092

Showing the first eight; more decompositions exist.
