Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452472, here are decompositions:

11 + 31452461 = 31452472
53 + 31452419 = 31452472
71 + 31452401 = 31452472
131 + 31452341 = 31452472
239 + 31452233 = 31452472
263 + 31452209 = 31452472
269 + 31452203 = 31452472
383 + 31452089 = 31452472

Showing the first eight; more decompositions exist.
