Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460466, here are decompositions:

53 + 31460413 = 31460466
67 + 31460399 = 31460466
97 + 31460369 = 31460466
127 + 31460339 = 31460466
137 + 31460329 = 31460466
173 + 31460293 = 31460466
199 + 31460267 = 31460466
269 + 31460197 = 31460466

Showing the first eight; more decompositions exist.
