Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501096, here are decompositions:

5 + 31501091 = 31501096
59 + 31501037 = 31501096
149 + 31500947 = 31501096
173 + 31500923 = 31501096
197 + 31500899 = 31501096
233 + 31500863 = 31501096
359 + 31500737 = 31501096
383 + 31500713 = 31501096

Showing the first eight; more decompositions exist.
