Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4280, here are decompositions:

7 + 4273 = 4280
19 + 4261 = 4280
37 + 4243 = 4280
61 + 4219 = 4280
79 + 4201 = 4280
103 + 4177 = 4280
127 + 4153 = 4280
151 + 4129 = 4280

Showing the first eight; more decompositions exist.
