Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466528, here are decompositions:

127 + 31466401 = 31466528
139 + 31466389 = 31466528
199 + 31466329 = 31466528
241 + 31466287 = 31466528
271 + 31466257 = 31466528
277 + 31466251 = 31466528
307 + 31466221 = 31466528
409 + 31466119 = 31466528

Showing the first eight; more decompositions exist.
