Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600496, here are decompositions:

3 + 31600493 = 31600496
43 + 31600453 = 31600496
73 + 31600423 = 31600496
139 + 31600357 = 31600496
163 + 31600333 = 31600496
223 + 31600273 = 31600496
307 + 31600189 = 31600496
379 + 31600117 = 31600496

Showing the first eight; more decompositions exist.
