Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501598, here are decompositions:

31 + 31501567 = 31501598
61 + 31501537 = 31501598
67 + 31501531 = 31501598
151 + 31501447 = 31501598
199 + 31501399 = 31501598
211 + 31501387 = 31501598
277 + 31501321 = 31501598
367 + 31501231 = 31501598

Showing the first eight; more decompositions exist.
