Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496422, here are decompositions:

3 + 31496419 = 31496422
5 + 31496417 = 31496422
53 + 31496369 = 31496422
101 + 31496321 = 31496422
281 + 31496141 = 31496422
443 + 31495979 = 31496422
563 + 31495859 = 31496422
761 + 31495661 = 31496422

Showing the first eight; more decompositions exist.
