Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496402, here are decompositions:

13 + 31496389 = 31496402
31 + 31496371 = 31496402
73 + 31496329 = 31496402
109 + 31496293 = 31496402
139 + 31496263 = 31496402
181 + 31496221 = 31496402
193 + 31496209 = 31496402
229 + 31496173 = 31496402

Showing the first eight; more decompositions exist.
