Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109878, here are decompositions:

5 + 109873 = 109878
19 + 109859 = 109878
29 + 109849 = 109878
31 + 109847 = 109878
37 + 109841 = 109878
47 + 109831 = 109878
59 + 109819 = 109878
71 + 109807 = 109878

Showing the first eight; more decompositions exist.
