Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446466, here are decompositions:

5 + 31446461 = 31446466
137 + 31446329 = 31446466
239 + 31446227 = 31446466
509 + 31445957 = 31446466
617 + 31445849 = 31446466
677 + 31445789 = 31446466
743 + 31445723 = 31446466
773 + 31445693 = 31446466

Showing the first eight; more decompositions exist.
