Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501674, here are decompositions:

5 + 31501669 = 31501674
13 + 31501661 = 31501674
41 + 31501633 = 31501674
53 + 31501621 = 31501674
107 + 31501567 = 31501674
137 + 31501537 = 31501674
151 + 31501523 = 31501674
227 + 31501447 = 31501674

Showing the first eight; more decompositions exist.
