Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460030, here are decompositions:

13 + 31460017 = 31460030
31 + 31459999 = 31460030
37 + 31459993 = 31460030
67 + 31459963 = 31460030
139 + 31459891 = 31460030
181 + 31459849 = 31460030
223 + 31459807 = 31460030
271 + 31459759 = 31460030

Showing the first eight; more decompositions exist.
