Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501596, here are decompositions:

13 + 31501583 = 31501596
29 + 31501567 = 31501596
59 + 31501537 = 31501596
73 + 31501523 = 31501596
149 + 31501447 = 31501596
163 + 31501433 = 31501596
193 + 31501403 = 31501596
197 + 31501399 = 31501596

Showing the first eight; more decompositions exist.
