Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567300, here are decompositions:

3 + 31567297 = 31567300
29 + 31567271 = 31567300
59 + 31567241 = 31567300
251 + 31567049 = 31567300
257 + 31567043 = 31567300
389 + 31566911 = 31567300
461 + 31566839 = 31567300
503 + 31566797 = 31567300

Showing the first eight; more decompositions exist.
