Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480846, here are decompositions:

17 + 31480829 = 31480846
53 + 31480793 = 31480846
83 + 31480763 = 31480846
113 + 31480733 = 31480846
197 + 31480649 = 31480846
317 + 31480529 = 31480846
479 + 31480367 = 31480846
557 + 31480289 = 31480846

Showing the first eight; more decompositions exist.
