Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466238, here are decompositions:

5 + 31466233 = 31466238
17 + 31466221 = 31466238
31 + 31466207 = 31466238
101 + 31466137 = 31466238
131 + 31466107 = 31466238
137 + 31466101 = 31466238
149 + 31466089 = 31466238
239 + 31465999 = 31466238

Showing the first eight; more decompositions exist.
