Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501862, here are decompositions:

13 + 31501849 = 31501862
31 + 31501831 = 31501862
43 + 31501819 = 31501862
103 + 31501759 = 31501862
163 + 31501699 = 31501862
193 + 31501669 = 31501862
229 + 31501633 = 31501862
241 + 31501621 = 31501862

Showing the first eight; more decompositions exist.
