Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4446, here are decompositions:

5 + 4441 = 4446
23 + 4423 = 4446
37 + 4409 = 4446
73 + 4373 = 4446
83 + 4363 = 4446
89 + 4357 = 4446
97 + 4349 = 4446
107 + 4339 = 4446

Showing the first eight; more decompositions exist.
