Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501174, here are decompositions:

83 + 31501091 = 31501174
113 + 31501061 = 31501174
137 + 31501037 = 31501174
197 + 31500977 = 31501174
227 + 31500947 = 31501174
233 + 31500941 = 31501174
251 + 31500923 = 31501174
311 + 31500863 = 31501174

Showing the first eight; more decompositions exist.
