Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466394, here are decompositions:

5 + 31466389 = 31466394
7 + 31466387 = 31466394
13 + 31466381 = 31466394
53 + 31466341 = 31466394
67 + 31466327 = 31466394
103 + 31466291 = 31466394
107 + 31466287 = 31466394
131 + 31466263 = 31466394

Showing the first eight; more decompositions exist.
