Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452412, here are decompositions:

11 + 31452401 = 31452412
71 + 31452341 = 31452412
179 + 31452233 = 31452412
239 + 31452173 = 31452412
281 + 31452131 = 31452412
419 + 31451993 = 31452412
443 + 31451969 = 31452412
503 + 31451909 = 31452412

Showing the first eight; more decompositions exist.
