Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600436, here are decompositions:

13 + 31600423 = 31600436
79 + 31600357 = 31600436
103 + 31600333 = 31600436
157 + 31600279 = 31600436
163 + 31600273 = 31600436
337 + 31600099 = 31600436
349 + 31600087 = 31600436
379 + 31600057 = 31600436

Showing the first eight; more decompositions exist.
