Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460016, here are decompositions:

17 + 31459999 = 31460016
23 + 31459993 = 31460016
53 + 31459963 = 31460016
67 + 31459949 = 31460016
79 + 31459937 = 31460016
157 + 31459859 = 31460016
163 + 31459853 = 31460016
167 + 31459849 = 31460016

Showing the first eight; more decompositions exist.
