Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501036, here are decompositions:

59 + 31500977 = 31501036
89 + 31500947 = 31501036
113 + 31500923 = 31501036
137 + 31500899 = 31501036
173 + 31500863 = 31501036
227 + 31500809 = 31501036
239 + 31500797 = 31501036
263 + 31500773 = 31501036

Showing the first eight; more decompositions exist.
