Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464166, here are decompositions:

17 + 31464149 = 31464166
23 + 31464143 = 31464166
29 + 31464137 = 31464166
257 + 31463909 = 31464166
269 + 31463897 = 31464166
317 + 31463849 = 31464166
359 + 31463807 = 31464166
449 + 31463717 = 31464166

Showing the first eight; more decompositions exist.
