Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508026, here are decompositions:

23 + 31508003 = 31508026
113 + 31507913 = 31508026
149 + 31507877 = 31508026
233 + 31507793 = 31508026
239 + 31507787 = 31508026
317 + 31507709 = 31508026
359 + 31507667 = 31508026
419 + 31507607 = 31508026

Showing the first eight; more decompositions exist.
