Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452474, here are decompositions:

13 + 31452461 = 31452474
23 + 31452451 = 31452474
73 + 31452401 = 31452474
107 + 31452367 = 31452474
173 + 31452301 = 31452474
191 + 31452283 = 31452474
233 + 31452241 = 31452474
241 + 31452233 = 31452474

Showing the first eight; more decompositions exist.
