Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574234, here are decompositions:

31 + 31574203 = 31574234
61 + 31574173 = 31574234
103 + 31574131 = 31574234
127 + 31574107 = 31574234
163 + 31574071 = 31574234
193 + 31574041 = 31574234
277 + 31573957 = 31574234
487 + 31573747 = 31574234

Showing the first eight; more decompositions exist.
