Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4230, here are decompositions:

11 + 4219 = 4230
13 + 4217 = 4230
19 + 4211 = 4230
29 + 4201 = 4230
53 + 4177 = 4230
71 + 4159 = 4230
73 + 4157 = 4230
97 + 4133 = 4230

Showing the first eight; more decompositions exist.
