Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457076, here are decompositions:

5 + 31457071 = 31457076
37 + 31457039 = 31457076
67 + 31457009 = 31457076
127 + 31456949 = 31457076
139 + 31456937 = 31457076
149 + 31456927 = 31457076
173 + 31456903 = 31457076
193 + 31456883 = 31457076

Showing the first eight; more decompositions exist.
