Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4442, here are decompositions:

19 + 4423 = 4442
79 + 4363 = 4442
103 + 4339 = 4442
181 + 4261 = 4442
199 + 4243 = 4442
211 + 4231 = 4442
223 + 4219 = 4442
241 + 4201 = 4442

Showing the first eight; more decompositions exist.
