Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547854, here are decompositions:

3 + 31547851 = 31547854
5 + 31547849 = 31547854
17 + 31547837 = 31547854
71 + 31547783 = 31547854
263 + 31547591 = 31547854
347 + 31547507 = 31547854
383 + 31547471 = 31547854
557 + 31547297 = 31547854

Showing the first eight; more decompositions exist.
