Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4480, here are decompositions:

17 + 4463 = 4480
23 + 4457 = 4480
29 + 4451 = 4480
59 + 4421 = 4480
71 + 4409 = 4480
83 + 4397 = 4480
89 + 4391 = 4480
107 + 4373 = 4480

Showing the first eight; more decompositions exist.
