Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482412, here are decompositions:

11 + 31482401 = 31482412
23 + 31482389 = 31482412
131 + 31482281 = 31482412
233 + 31482179 = 31482412
239 + 31482173 = 31482412
293 + 31482119 = 31482412
431 + 31481981 = 31482412
461 + 31481951 = 31482412

Showing the first eight; more decompositions exist.
