Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625316, here are decompositions:

13 + 31625303 = 31625316
53 + 31625263 = 31625316
137 + 31625179 = 31625316
167 + 31625149 = 31625316
257 + 31625059 = 31625316
277 + 31625039 = 31625316
337 + 31624979 = 31625316
389 + 31624927 = 31625316

Showing the first eight; more decompositions exist.
