Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466544, here are decompositions:

41 + 31466503 = 31466544
157 + 31466387 = 31466544
163 + 31466381 = 31466544
257 + 31466287 = 31466544
281 + 31466263 = 31466544
293 + 31466251 = 31466544
311 + 31466233 = 31466544
337 + 31466207 = 31466544

Showing the first eight; more decompositions exist.
