Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446366, here are decompositions:

5 + 31446361 = 31446366
37 + 31446329 = 31446366
43 + 31446323 = 31446366
109 + 31446257 = 31446366
113 + 31446253 = 31446366
137 + 31446229 = 31446366
139 + 31446227 = 31446366
199 + 31446167 = 31446366

Showing the first eight; more decompositions exist.
