Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4260, here are decompositions:

7 + 4253 = 4260
17 + 4243 = 4260
19 + 4241 = 4260
29 + 4231 = 4260
31 + 4229 = 4260
41 + 4219 = 4260
43 + 4217 = 4260
59 + 4201 = 4260

Showing the first eight; more decompositions exist.
