Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466254, here are decompositions:

3 + 31466251 = 31466254
5 + 31466249 = 31466254
47 + 31466207 = 31466254
191 + 31466063 = 31466254
251 + 31466003 = 31466254
557 + 31465697 = 31466254
593 + 31465661 = 31466254
653 + 31465601 = 31466254

Showing the first eight; more decompositions exist.
