Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452464, here are decompositions:

3 + 31452461 = 31452464
13 + 31452451 = 31452464
97 + 31452367 = 31452464
163 + 31452301 = 31452464
181 + 31452283 = 31452464
223 + 31452241 = 31452464
283 + 31452181 = 31452464
367 + 31452097 = 31452464

Showing the first eight; more decompositions exist.
