Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446492, here are decompositions:

31 + 31446461 = 31446492
53 + 31446439 = 31446492
131 + 31446361 = 31446492
151 + 31446341 = 31446492
163 + 31446329 = 31446492
239 + 31446253 = 31446492
241 + 31446251 = 31446492
251 + 31446241 = 31446492

Showing the first eight; more decompositions exist.
