Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4100, here are decompositions:

7 + 4093 = 4100
43 + 4057 = 4100
73 + 4027 = 4100
79 + 4021 = 4100
97 + 4003 = 4100
157 + 3943 = 4100
181 + 3919 = 4100
193 + 3907 = 4100

Showing the first eight; more decompositions exist.
