Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607666, here are decompositions:

37 + 31607629 = 31607666
67 + 31607599 = 31607666
163 + 31607503 = 31607666
193 + 31607473 = 31607666
367 + 31607299 = 31607666
373 + 31607293 = 31607666
439 + 31607227 = 31607666
619 + 31607047 = 31607666

Showing the first eight; more decompositions exist.
