Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607600, here are decompositions:

19 + 31607581 = 31607600
97 + 31607503 = 31607600
127 + 31607473 = 31607600
139 + 31607461 = 31607600
151 + 31607449 = 31607600
307 + 31607293 = 31607600
337 + 31607263 = 31607600
373 + 31607227 = 31607600

Showing the first eight; more decompositions exist.
