Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457050, here are decompositions:

11 + 31457039 = 31457050
41 + 31457009 = 31457050
101 + 31456949 = 31457050
113 + 31456937 = 31457050
167 + 31456883 = 31457050
263 + 31456787 = 31457050
269 + 31456781 = 31457050
281 + 31456769 = 31457050

Showing the first eight; more decompositions exist.
