Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460018, here are decompositions:

19 + 31459999 = 31460018
127 + 31459891 = 31460018
211 + 31459807 = 31460018
367 + 31459651 = 31460018
397 + 31459621 = 31460018
409 + 31459609 = 31460018
619 + 31459399 = 31460018
631 + 31459387 = 31460018

Showing the first eight; more decompositions exist.
