Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607318, here are decompositions:

19 + 31607299 = 31607318
37 + 31607281 = 31607318
181 + 31607137 = 31607318
271 + 31607047 = 31607318
367 + 31606951 = 31607318
439 + 31606879 = 31607318
577 + 31606741 = 31607318
607 + 31606711 = 31607318

Showing the first eight; more decompositions exist.
