Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501048, here are decompositions:

11 + 31501037 = 31501048
71 + 31500977 = 31501048
101 + 31500947 = 31501048
107 + 31500941 = 31501048
149 + 31500899 = 31501048
239 + 31500809 = 31501048
251 + 31500797 = 31501048
281 + 31500767 = 31501048

Showing the first eight; more decompositions exist.
