Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460136, here are decompositions:

7 + 31460129 = 31460136
73 + 31460063 = 31460136
83 + 31460053 = 31460136
137 + 31459999 = 31460136
173 + 31459963 = 31460136
199 + 31459937 = 31460136
277 + 31459859 = 31460136
283 + 31459853 = 31460136

Showing the first eight; more decompositions exist.
