Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496360, here are decompositions:

31 + 31496329 = 31496360
43 + 31496317 = 31496360
67 + 31496293 = 31496360
97 + 31496263 = 31496360
139 + 31496221 = 31496360
151 + 31496209 = 31496360
199 + 31496161 = 31496360
241 + 31496119 = 31496360

Showing the first eight; more decompositions exist.
