Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463824, here are decompositions:

17 + 31463807 = 31463824
107 + 31463717 = 31463824
233 + 31463591 = 31463824
317 + 31463507 = 31463824
347 + 31463477 = 31463824
461 + 31463363 = 31463824
503 + 31463321 = 31463824
563 + 31463261 = 31463824

Showing the first eight; more decompositions exist.
