Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457300, here are decompositions:

3 + 31457297 = 31457300
13 + 31457287 = 31457300
31 + 31457269 = 31457300
73 + 31457227 = 31457300
97 + 31457203 = 31457300
151 + 31457149 = 31457300
181 + 31457119 = 31457300
229 + 31457071 = 31457300

Showing the first eight; more decompositions exist.
