Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446062, here are decompositions:

31 + 31446031 = 31446062
79 + 31445983 = 31446062
103 + 31445959 = 31446062
199 + 31445863 = 31446062
211 + 31445851 = 31446062
229 + 31445833 = 31446062
421 + 31445641 = 31446062
523 + 31445539 = 31446062

Showing the first eight; more decompositions exist.
