Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4218, here are decompositions:

7 + 4211 = 4218
17 + 4201 = 4218
41 + 4177 = 4218
59 + 4159 = 4218
61 + 4157 = 4218
79 + 4139 = 4218
89 + 4129 = 4218
107 + 4111 = 4218

Showing the first eight; more decompositions exist.
