Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446722, here are decompositions:

283 + 31446439 = 31446722
499 + 31446223 = 31446722
661 + 31446061 = 31446722
691 + 31446031 = 31446722
739 + 31445983 = 31446722
859 + 31445863 = 31446722
1279 + 31445443 = 31446722
1291 + 31445431 = 31446722

Showing the first eight; more decompositions exist.
