Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4156, here are decompositions:

3 + 4153 = 4156
17 + 4139 = 4156
23 + 4133 = 4156
29 + 4127 = 4156
83 + 4073 = 4156
107 + 4049 = 4156
137 + 4019 = 4156
149 + 4007 = 4156

Showing the first eight; more decompositions exist.
