Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4212, here are decompositions:

11 + 4201 = 4212
53 + 4159 = 4212
59 + 4153 = 4212
73 + 4139 = 4212
79 + 4133 = 4212
83 + 4129 = 4212
101 + 4111 = 4212
113 + 4099 = 4212

Showing the first eight; more decompositions exist.
