Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600472, here are decompositions:

19 + 31600453 = 31600472
31 + 31600441 = 31600472
139 + 31600333 = 31600472
181 + 31600291 = 31600472
193 + 31600279 = 31600472
199 + 31600273 = 31600472
271 + 31600201 = 31600472
283 + 31600189 = 31600472

Showing the first eight; more decompositions exist.
