Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607630, here are decompositions:

31 + 31607599 = 31607630
79 + 31607551 = 31607630
127 + 31607503 = 31607630
157 + 31607473 = 31607630
181 + 31607449 = 31607630
331 + 31607299 = 31607630
337 + 31607293 = 31607630
349 + 31607281 = 31607630

Showing the first eight; more decompositions exist.
