Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599408, here are decompositions:

19 + 31599389 = 31599408
59 + 31599349 = 31599408
67 + 31599341 = 31599408
101 + 31599307 = 31599408
149 + 31599259 = 31599408
251 + 31599157 = 31599408
307 + 31599101 = 31599408
349 + 31599059 = 31599408

Showing the first eight; more decompositions exist.
