Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4386, here are decompositions:
- 13 + 4373 = 4386
- 23 + 4363 = 4386
- 29 + 4357 = 4386
- 37 + 4349 = 4386
- 47 + 4339 = 4386
- 59 + 4327 = 4386
- 89 + 4297 = 4386
- 97 + 4289 = 4386
Showing the first eight; more decompositions exist.
