Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452344, here are decompositions:

3 + 31452341 = 31452344
43 + 31452301 = 31452344
61 + 31452283 = 31452344
103 + 31452241 = 31452344
163 + 31452181 = 31452344
223 + 31452121 = 31452344
283 + 31452061 = 31452344
331 + 31452013 = 31452344

Showing the first eight; more decompositions exist.
