Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599436, here are decompositions:

5 + 31599431 = 31599436
47 + 31599389 = 31599436
83 + 31599353 = 31599436
263 + 31599173 = 31599436
503 + 31598933 = 31599436
509 + 31598927 = 31599436
563 + 31598873 = 31599436
569 + 31598867 = 31599436

Showing the first eight; more decompositions exist.
