Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501606, here are decompositions:

23 + 31501583 = 31501606
83 + 31501523 = 31501606
173 + 31501433 = 31501606
179 + 31501427 = 31501606
197 + 31501409 = 31501606
293 + 31501313 = 31501606
359 + 31501247 = 31501606
569 + 31501037 = 31501606

Showing the first eight; more decompositions exist.
