Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463604, here are decompositions:

13 + 31463591 = 31463604
17 + 31463587 = 31463604
71 + 31463533 = 31463604
97 + 31463507 = 31463604
127 + 31463477 = 31463604
197 + 31463407 = 31463604
241 + 31463363 = 31463604
251 + 31463353 = 31463604

Showing the first eight; more decompositions exist.
