Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109854, here are decompositions:

5 + 109849 = 109854
7 + 109847 = 109854
11 + 109843 = 109854
13 + 109841 = 109854
23 + 109831 = 109854
47 + 109807 = 109854
61 + 109793 = 109854
103 + 109751 = 109854

Showing the first eight; more decompositions exist.
