Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4878, here are decompositions:

7 + 4871 = 4878
17 + 4861 = 4878
47 + 4831 = 4878
61 + 4817 = 4878
79 + 4799 = 4878
89 + 4789 = 4878
127 + 4751 = 4878
149 + 4729 = 4878

Showing the first eight; more decompositions exist.
