Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4840, here are decompositions:

23 + 4817 = 4840
41 + 4799 = 4840
47 + 4793 = 4840
53 + 4787 = 4840
89 + 4751 = 4840
107 + 4733 = 4840
137 + 4703 = 4840
149 + 4691 = 4840

Showing the first eight; more decompositions exist.
