Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466564, here are decompositions:

61 + 31466503 = 31466564
163 + 31466401 = 31466564
223 + 31466341 = 31466564
277 + 31466287 = 31466564
307 + 31466257 = 31466564
313 + 31466251 = 31466564
331 + 31466233 = 31466564
421 + 31466143 = 31466564

Showing the first eight; more decompositions exist.
