Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4920, here are decompositions:

11 + 4909 = 4920
17 + 4903 = 4920
31 + 4889 = 4920
43 + 4877 = 4920
59 + 4861 = 4920
89 + 4831 = 4920
103 + 4817 = 4920
107 + 4813 = 4920

Showing the first eight; more decompositions exist.
