Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501464, here are decompositions:

17 + 31501447 = 31501464
31 + 31501433 = 31501464
37 + 31501427 = 31501464
61 + 31501403 = 31501464
103 + 31501361 = 31501464
131 + 31501333 = 31501464
151 + 31501313 = 31501464
233 + 31501231 = 31501464

Showing the first eight; more decompositions exist.
