Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452404, here are decompositions:

3 + 31452401 = 31452404
37 + 31452367 = 31452404
103 + 31452301 = 31452404
163 + 31452241 = 31452404
223 + 31452181 = 31452404
283 + 31452121 = 31452404
307 + 31452097 = 31452404
397 + 31452007 = 31452404

Showing the first eight; more decompositions exist.
