Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457024, here are decompositions:

97 + 31456927 = 31457024
283 + 31456741 = 31457024
373 + 31456651 = 31457024
523 + 31456501 = 31457024
733 + 31456291 = 31457024
787 + 31456237 = 31457024
1021 + 31456003 = 31457024
1063 + 31455961 = 31457024

Showing the first eight; more decompositions exist.
