Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508082, here are decompositions:

5 + 31508077 = 31508082
43 + 31508039 = 31508082
79 + 31508003 = 31508082
101 + 31507981 = 31508082
131 + 31507951 = 31508082
181 + 31507901 = 31508082
293 + 31507789 = 31508082
311 + 31507771 = 31508082

Showing the first eight; more decompositions exist.
