Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4210, here are decompositions:

53 + 4157 = 4210
71 + 4139 = 4210
83 + 4127 = 4210
131 + 4079 = 4210
137 + 4073 = 4210
191 + 4019 = 4210
197 + 4013 = 4210
263 + 3947 = 4210

Showing the first eight; more decompositions exist.
