Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4270, here are decompositions:

11 + 4259 = 4270
17 + 4253 = 4270
29 + 4241 = 4270
41 + 4229 = 4270
53 + 4217 = 4270
59 + 4211 = 4270
113 + 4157 = 4270
131 + 4139 = 4270

Showing the first eight; more decompositions exist.
