Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501576, here are decompositions:

53 + 31501523 = 31501576
149 + 31501427 = 31501576
167 + 31501409 = 31501576
173 + 31501403 = 31501576
263 + 31501313 = 31501576
347 + 31501229 = 31501576
599 + 31500977 = 31501576
653 + 31500923 = 31501576

Showing the first eight; more decompositions exist.
