Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600004, here are decompositions:

3 + 31600001 = 31600004
103 + 31599901 = 31600004
127 + 31599877 = 31600004
181 + 31599823 = 31600004
193 + 31599811 = 31600004
223 + 31599781 = 31600004
277 + 31599727 = 31600004
691 + 31599313 = 31600004

Showing the first eight; more decompositions exist.
