Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466020, here are decompositions:

17 + 31466003 = 31466020
41 + 31465979 = 31466020
191 + 31465829 = 31466020
239 + 31465781 = 31466020
263 + 31465757 = 31466020
293 + 31465727 = 31466020
347 + 31465673 = 31466020
359 + 31465661 = 31466020

Showing the first eight; more decompositions exist.
