Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4142, here are decompositions:

3 + 4139 = 4142
13 + 4129 = 4142
31 + 4111 = 4142
43 + 4099 = 4142
139 + 4003 = 4142
199 + 3943 = 4142
211 + 3931 = 4142
223 + 3919 = 4142

Showing the first eight; more decompositions exist.
