Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446392, here are decompositions:

31 + 31446361 = 31446392
139 + 31446253 = 31446392
151 + 31446241 = 31446392
163 + 31446229 = 31446392
181 + 31446211 = 31446392
331 + 31446061 = 31446392
409 + 31445983 = 31446392
433 + 31445959 = 31446392

Showing the first eight; more decompositions exist.
