Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4380, here are decompositions:

7 + 4373 = 4380
17 + 4363 = 4380
23 + 4357 = 4380
31 + 4349 = 4380
41 + 4339 = 4380
43 + 4337 = 4380
53 + 4327 = 4380
83 + 4297 = 4380

Showing the first eight; more decompositions exist.
