Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466450, here are decompositions:

61 + 31466389 = 31466450
109 + 31466341 = 31466450
163 + 31466287 = 31466450
193 + 31466257 = 31466450
199 + 31466251 = 31466450
229 + 31466221 = 31466450
277 + 31466173 = 31466450
307 + 31466143 = 31466450

Showing the first eight; more decompositions exist.
