Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596408, here are decompositions:

5 + 31596403 = 31596408
7 + 31596401 = 31596408
17 + 31596391 = 31596408
29 + 31596379 = 31596408
97 + 31596311 = 31596408
101 + 31596307 = 31596408
199 + 31596209 = 31596408
257 + 31596151 = 31596408

Showing the first eight; more decompositions exist.
