Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488204, here are decompositions:

43 + 31488161 = 31488204
67 + 31488137 = 31488204
71 + 31488133 = 31488204
103 + 31488101 = 31488204
113 + 31488091 = 31488204
151 + 31488053 = 31488204
173 + 31488031 = 31488204
191 + 31488013 = 31488204

Showing the first eight; more decompositions exist.
