Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446422, here are decompositions:

61 + 31446361 = 31446422
181 + 31446241 = 31446422
193 + 31446229 = 31446422
199 + 31446223 = 31446422
211 + 31446211 = 31446422
439 + 31445983 = 31446422
463 + 31445959 = 31446422
571 + 31445851 = 31446422

Showing the first eight; more decompositions exist.
