Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496424, here are decompositions:

5 + 31496419 = 31496424
7 + 31496417 = 31496424
53 + 31496371 = 31496424
103 + 31496321 = 31496424
107 + 31496317 = 31496424
131 + 31496293 = 31496424
163 + 31496261 = 31496424
251 + 31496173 = 31496424

Showing the first eight; more decompositions exist.
