Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458974, here are decompositions:

7 + 31458967 = 31458974
37 + 31458937 = 31458974
61 + 31458913 = 31458974
67 + 31458907 = 31458974
73 + 31458901 = 31458974
271 + 31458703 = 31458974
277 + 31458697 = 31458974
307 + 31458667 = 31458974

Showing the first eight; more decompositions exist.
