Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482382, here are decompositions:

89 + 31482293 = 31482382
101 + 31482281 = 31482382
263 + 31482119 = 31482382
293 + 31482089 = 31482382
401 + 31481981 = 31482382
431 + 31481951 = 31482382
443 + 31481939 = 31482382
461 + 31481921 = 31482382

Showing the first eight; more decompositions exist.
