Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501632, here are decompositions:

11 + 31501621 = 31501632
13 + 31501619 = 31501632
101 + 31501531 = 31501632
109 + 31501523 = 31501632
199 + 31501433 = 31501632
223 + 31501409 = 31501632
229 + 31501403 = 31501632
233 + 31501399 = 31501632

Showing the first eight; more decompositions exist.
