Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532118, here are decompositions:

5 + 31532113 = 31532118
29 + 31532089 = 31532118
47 + 31532071 = 31532118
97 + 31532021 = 31532118
151 + 31531967 = 31532118
197 + 31531921 = 31532118
367 + 31531751 = 31532118
439 + 31531679 = 31532118

Showing the first eight; more decompositions exist.
