Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482760, here are decompositions:

17 + 31482743 = 31482760
53 + 31482707 = 31482760
173 + 31482587 = 31482760
191 + 31482569 = 31482760
251 + 31482509 = 31482760
359 + 31482401 = 31482760
467 + 31482293 = 31482760
479 + 31482281 = 31482760

Showing the first eight; more decompositions exist.
