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.
