Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576004, here are decompositions:

3 + 31576001 = 31576004
13 + 31575991 = 31576004
67 + 31575937 = 31576004
127 + 31575877 = 31576004
181 + 31575823 = 31576004
211 + 31575793 = 31576004
277 + 31575727 = 31576004
307 + 31575697 = 31576004

Showing the first eight; more decompositions exist.
