Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496330, here are decompositions:

13 + 31496317 = 31496330
37 + 31496293 = 31496330
67 + 31496263 = 31496330
109 + 31496221 = 31496330
157 + 31496173 = 31496330
211 + 31496119 = 31496330
409 + 31495921 = 31496330
433 + 31495897 = 31496330

Showing the first eight; more decompositions exist.
