Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466486, here are decompositions:

97 + 31466389 = 31466486
157 + 31466329 = 31466486
199 + 31466287 = 31466486
223 + 31466263 = 31466486
229 + 31466257 = 31466486
313 + 31466173 = 31466486
349 + 31466137 = 31466486
367 + 31466119 = 31466486

Showing the first eight; more decompositions exist.
