Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4886, here are decompositions:

73 + 4813 = 4886
97 + 4789 = 4886
103 + 4783 = 4886
127 + 4759 = 4886
157 + 4729 = 4886
163 + 4723 = 4886
223 + 4663 = 4886
229 + 4657 = 4886

Showing the first eight; more decompositions exist.
