Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466070, here are decompositions:

7 + 31466063 = 31466070
17 + 31466053 = 31466070
19 + 31466051 = 31466070
67 + 31466003 = 31466070
71 + 31465999 = 31466070
179 + 31465891 = 31466070
191 + 31465879 = 31466070
239 + 31465831 = 31466070

Showing the first eight; more decompositions exist.
