Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534152, here are decompositions:

11 + 31534141 = 31534152
31 + 31534121 = 31534152
73 + 31534079 = 31534152
79 + 31534073 = 31534152
101 + 31534051 = 31534152
173 + 31533979 = 31534152
193 + 31533959 = 31534152
229 + 31533923 = 31534152

Showing the first eight; more decompositions exist.
