Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501066, here are decompositions:

5 + 31501061 = 31501066
29 + 31501037 = 31501066
89 + 31500977 = 31501066
167 + 31500899 = 31501066
257 + 31500809 = 31501066
269 + 31500797 = 31501066
293 + 31500773 = 31501066
347 + 31500719 = 31501066

Showing the first eight; more decompositions exist.
