Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460006, here are decompositions:

7 + 31459999 = 31460006
13 + 31459993 = 31460006
43 + 31459963 = 31460006
157 + 31459849 = 31460006
199 + 31459807 = 31460006
283 + 31459723 = 31460006
373 + 31459633 = 31460006
397 + 31459609 = 31460006

Showing the first eight; more decompositions exist.
