Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486026, here are decompositions:

17 + 31486009 = 31486026
53 + 31485973 = 31486026
67 + 31485959 = 31486026
73 + 31485953 = 31486026
109 + 31485917 = 31486026
137 + 31485889 = 31486026
193 + 31485833 = 31486026
223 + 31485803 = 31486026

Showing the first eight; more decompositions exist.
