Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508056, here are decompositions:

17 + 31508039 = 31508056
29 + 31508027 = 31508056
53 + 31508003 = 31508056
179 + 31507877 = 31508056
233 + 31507823 = 31508056
263 + 31507793 = 31508056
269 + 31507787 = 31508056
317 + 31507739 = 31508056

Showing the first eight; more decompositions exist.
