Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501692, here are decompositions:

23 + 31501669 = 31501692
31 + 31501661 = 31501692
59 + 31501633 = 31501692
71 + 31501621 = 31501692
73 + 31501619 = 31501692
109 + 31501583 = 31501692
283 + 31501409 = 31501692
293 + 31501399 = 31501692

Showing the first eight; more decompositions exist.
