Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461464, here are decompositions:

7 + 31461457 = 31461464
37 + 31461427 = 31461464
61 + 31461403 = 31461464
103 + 31461361 = 31461464
163 + 31461301 = 31461464
211 + 31461253 = 31461464
241 + 31461223 = 31461464
271 + 31461193 = 31461464

Showing the first eight; more decompositions exist.
