Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464954, here are decompositions:

7 + 31464947 = 31464954
13 + 31464941 = 31464954
71 + 31464883 = 31464954
127 + 31464827 = 31464954
167 + 31464787 = 31464954
173 + 31464781 = 31464954
197 + 31464757 = 31464954
223 + 31464731 = 31464954

Showing the first eight; more decompositions exist.
