Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508014, here are decompositions:

11 + 31508003 = 31508014
23 + 31507991 = 31508014
101 + 31507913 = 31508014
113 + 31507901 = 31508014
137 + 31507877 = 31508014
191 + 31507823 = 31508014
227 + 31507787 = 31508014
311 + 31507703 = 31508014

Showing the first eight; more decompositions exist.
