Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109866, here are decompositions:

7 + 109859 = 109866
17 + 109849 = 109866
19 + 109847 = 109866
23 + 109843 = 109866
37 + 109829 = 109866
47 + 109819 = 109866
59 + 109807 = 109866
73 + 109793 = 109866

Showing the first eight; more decompositions exist.
