Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482454, here are decompositions:

53 + 31482401 = 31482454
173 + 31482281 = 31482454
197 + 31482257 = 31482454
281 + 31482173 = 31482454
503 + 31481951 = 31482454
587 + 31481867 = 31482454
617 + 31481837 = 31482454
701 + 31481753 = 31482454

Showing the first eight; more decompositions exist.
