Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4392, here are decompositions:

19 + 4373 = 4392
29 + 4363 = 4392
43 + 4349 = 4392
53 + 4339 = 4392
103 + 4289 = 4392
109 + 4283 = 4392
131 + 4261 = 4392
139 + 4253 = 4392

Showing the first eight; more decompositions exist.
