Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466344, here are decompositions:

3 + 31466341 = 31466344
17 + 31466327 = 31466344
53 + 31466291 = 31466344
137 + 31466207 = 31466344
281 + 31466063 = 31466344
293 + 31466051 = 31466344
563 + 31465781 = 31466344
587 + 31465757 = 31466344

Showing the first eight; more decompositions exist.
