Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452462, here are decompositions:

11 + 31452451 = 31452462
43 + 31452419 = 31452462
61 + 31452401 = 31452462
179 + 31452283 = 31452462
229 + 31452233 = 31452462
263 + 31452199 = 31452462
281 + 31452181 = 31452462
331 + 31452131 = 31452462

Showing the first eight; more decompositions exist.
