Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508062, here are decompositions:

23 + 31508039 = 31508062
59 + 31508003 = 31508062
71 + 31507991 = 31508062
149 + 31507913 = 31508062
239 + 31507823 = 31508062
269 + 31507793 = 31508062
353 + 31507709 = 31508062
359 + 31507703 = 31508062

Showing the first eight; more decompositions exist.
