Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4440, here are decompositions:

17 + 4423 = 4440
19 + 4421 = 4440
31 + 4409 = 4440
43 + 4397 = 4440
67 + 4373 = 4440
83 + 4357 = 4440
101 + 4339 = 4440
103 + 4337 = 4440

Showing the first eight; more decompositions exist.
