Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576006, here are decompositions:

3 + 31576003 = 31576006
5 + 31576001 = 31576006
83 + 31575923 = 31576006
89 + 31575917 = 31576006
107 + 31575899 = 31576006
113 + 31575893 = 31576006
167 + 31575839 = 31576006
173 + 31575833 = 31576006

Showing the first eight; more decompositions exist.
