Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480546, here are decompositions:

17 + 31480529 = 31480546
113 + 31480433 = 31480546
173 + 31480373 = 31480546
179 + 31480367 = 31480546
197 + 31480349 = 31480546
257 + 31480289 = 31480546
443 + 31480103 = 31480546
467 + 31480079 = 31480546

Showing the first eight; more decompositions exist.
