Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501726, here are decompositions:

5 + 31501721 = 31501726
107 + 31501619 = 31501726
293 + 31501433 = 31501726
317 + 31501409 = 31501726
479 + 31501247 = 31501726
827 + 31500899 = 31501726
863 + 31500863 = 31501726
929 + 31500797 = 31501726

Showing the first eight; more decompositions exist.
