Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460252, here are decompositions:

79 + 31460173 = 31460252
199 + 31460053 = 31460252
601 + 31459651 = 31460252
619 + 31459633 = 31460252
631 + 31459621 = 31460252
643 + 31459609 = 31460252
853 + 31459399 = 31460252
991 + 31459261 = 31460252

Showing the first eight; more decompositions exist.
