Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4140, here are decompositions:

7 + 4133 = 4140
11 + 4129 = 4140
13 + 4127 = 4140
29 + 4111 = 4140
41 + 4099 = 4140
47 + 4093 = 4140
61 + 4079 = 4140
67 + 4073 = 4140

Showing the first eight; more decompositions exist.
