Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4378, here are decompositions:
- 5 + 4373 = 4378
- 29 + 4349 = 4378
- 41 + 4337 = 4378
- 89 + 4289 = 4378
- 107 + 4271 = 4378
- 137 + 4241 = 4378
- 149 + 4229 = 4378
- 167 + 4211 = 4378
Showing the first eight; more decompositions exist.
