Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466386, here are decompositions:

5 + 31466381 = 31466386
59 + 31466327 = 31466386
137 + 31466249 = 31466386
179 + 31466207 = 31466386
383 + 31466003 = 31466386
557 + 31465829 = 31466386
659 + 31465727 = 31466386
839 + 31465547 = 31466386

Showing the first eight; more decompositions exist.
