Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501832, here are decompositions:

13 + 31501819 = 31501832
73 + 31501759 = 31501832
163 + 31501669 = 31501832
199 + 31501633 = 31501832
211 + 31501621 = 31501832
433 + 31501399 = 31501832
499 + 31501333 = 31501832
601 + 31501231 = 31501832

Showing the first eight; more decompositions exist.
