Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4870, here are decompositions:

53 + 4817 = 4870
71 + 4799 = 4870
83 + 4787 = 4870
137 + 4733 = 4870
149 + 4721 = 4870
167 + 4703 = 4870
179 + 4691 = 4870
191 + 4679 = 4870

Showing the first eight; more decompositions exist.
