Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607622, here are decompositions:

23 + 31607599 = 31607622
41 + 31607581 = 31607622
43 + 31607579 = 31607622
71 + 31607551 = 31607622
149 + 31607473 = 31607622
173 + 31607449 = 31607622
199 + 31607423 = 31607622
223 + 31607399 = 31607622

Showing the first eight; more decompositions exist.
