Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466402, here are decompositions:

13 + 31466389 = 31466402
61 + 31466341 = 31466402
73 + 31466329 = 31466402
139 + 31466263 = 31466402
151 + 31466251 = 31466402
181 + 31466221 = 31466402
229 + 31466173 = 31466402
283 + 31466119 = 31466402

Showing the first eight; more decompositions exist.
