Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4070, here are decompositions:

13 + 4057 = 4070
19 + 4051 = 4070
43 + 4027 = 4070
67 + 4003 = 4070
103 + 3967 = 4070
127 + 3943 = 4070
139 + 3931 = 4070
151 + 3919 = 4070

Showing the first eight; more decompositions exist.
