Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598004, here are decompositions:

7 + 31597997 = 31598004
17 + 31597987 = 31598004
43 + 31597961 = 31598004
71 + 31597933 = 31598004
127 + 31597877 = 31598004
131 + 31597873 = 31598004
181 + 31597823 = 31598004
211 + 31597793 = 31598004

Showing the first eight; more decompositions exist.
