Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576002, here are decompositions:

11 + 31575991 = 31576002
79 + 31575923 = 31576002
103 + 31575899 = 31576002
109 + 31575893 = 31576002
163 + 31575839 = 31576002
173 + 31575829 = 31576002
179 + 31575823 = 31576002
233 + 31575769 = 31576002

Showing the first eight; more decompositions exist.
