Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112878, here are decompositions:

19 + 112859 = 112878
47 + 112831 = 112878
71 + 112807 = 112878
79 + 112799 = 112878
107 + 112771 = 112878
137 + 112741 = 112878
191 + 112687 = 112878
257 + 112621 = 112878

Showing the first eight; more decompositions exist.
