Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457044, here are decompositions:

5 + 31457039 = 31457044
107 + 31456937 = 31457044
257 + 31456787 = 31457044
263 + 31456781 = 31457044
317 + 31456727 = 31457044
557 + 31456487 = 31457044
683 + 31456361 = 31457044
797 + 31456247 = 31457044

Showing the first eight; more decompositions exist.
