Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4356, here are decompositions:

7 + 4349 = 4356
17 + 4339 = 4356
19 + 4337 = 4356
29 + 4327 = 4356
59 + 4297 = 4356
67 + 4289 = 4356
73 + 4283 = 4356
83 + 4273 = 4356

Showing the first eight; more decompositions exist.
