Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508252, here are decompositions:

19 + 31508233 = 31508252
73 + 31508179 = 31508252
109 + 31508143 = 31508252
151 + 31508101 = 31508252
271 + 31507981 = 31508252
313 + 31507939 = 31508252
331 + 31507921 = 31508252
463 + 31507789 = 31508252

Showing the first eight; more decompositions exist.
