Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508006, here are decompositions:

3 + 31508003 = 31508006
67 + 31507939 = 31508006
109 + 31507897 = 31508006
307 + 31507699 = 31508006
373 + 31507633 = 31508006
433 + 31507573 = 31508006
499 + 31507507 = 31508006
547 + 31507459 = 31508006

Showing the first eight; more decompositions exist.
