Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115854, here are decompositions:

5 + 115849 = 115854
17 + 115837 = 115854
23 + 115831 = 115854
31 + 115823 = 115854
43 + 115811 = 115854
47 + 115807 = 115854
61 + 115793 = 115854
71 + 115783 = 115854

Showing the first eight; more decompositions exist.
