Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607300, here are decompositions:

3 + 31607297 = 31607300
7 + 31607293 = 31607300
19 + 31607281 = 31607300
37 + 31607263 = 31607300
73 + 31607227 = 31607300
163 + 31607137 = 31607300
199 + 31607101 = 31607300
337 + 31606963 = 31607300

Showing the first eight; more decompositions exist.
