Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74878, here are decompositions:

5 + 74873 = 74878
17 + 74861 = 74878
47 + 74831 = 74878
107 + 74771 = 74878
131 + 74747 = 74878
149 + 74729 = 74878
179 + 74699 = 74878
191 + 74687 = 74878

Showing the first eight; more decompositions exist.
