Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4158, here are decompositions:

5 + 4153 = 4158
19 + 4139 = 4158
29 + 4129 = 4158
31 + 4127 = 4158
47 + 4111 = 4158
59 + 4099 = 4158
67 + 4091 = 4158
79 + 4079 = 4158

Showing the first eight; more decompositions exist.
