Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4820, here are decompositions:

3 + 4817 = 4820
7 + 4813 = 4820
19 + 4801 = 4820
31 + 4789 = 4820
37 + 4783 = 4820
61 + 4759 = 4820
97 + 4723 = 4820
157 + 4663 = 4820

Showing the first eight; more decompositions exist.
