Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508104, here are decompositions:

3 + 31508101 = 31508104
11 + 31508093 = 31508104
101 + 31508003 = 31508104
113 + 31507991 = 31508104
191 + 31507913 = 31508104
227 + 31507877 = 31508104
281 + 31507823 = 31508104
311 + 31507793 = 31508104

Showing the first eight; more decompositions exist.
