Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4450, here are decompositions:

3 + 4447 = 4450
29 + 4421 = 4450
41 + 4409 = 4450
53 + 4397 = 4450
59 + 4391 = 4450
101 + 4349 = 4450
113 + 4337 = 4450
167 + 4283 = 4450

Showing the first eight; more decompositions exist.
