Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496672, here are decompositions:

3 + 31496669 = 31496672
61 + 31496611 = 31496672
73 + 31496599 = 31496672
79 + 31496593 = 31496672
223 + 31496449 = 31496672
283 + 31496389 = 31496672
379 + 31496293 = 31496672
409 + 31496263 = 31496672

Showing the first eight; more decompositions exist.
