Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4420, here are decompositions:

11 + 4409 = 4420
23 + 4397 = 4420
29 + 4391 = 4420
47 + 4373 = 4420
71 + 4349 = 4420
83 + 4337 = 4420
131 + 4289 = 4420
137 + 4283 = 4420

Showing the first eight; more decompositions exist.
