Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596000, here are decompositions:

11 + 31595989 = 31596000
17 + 31595983 = 31596000
31 + 31595969 = 31596000
71 + 31595929 = 31596000
127 + 31595873 = 31596000
131 + 31595869 = 31596000
167 + 31595833 = 31596000
193 + 31595807 = 31596000

Showing the first eight; more decompositions exist.
