Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4438, here are decompositions:
- 17 + 4421 = 4438
- 29 + 4409 = 4438
- 41 + 4397 = 4438
- 47 + 4391 = 4438
- 89 + 4349 = 4438
- 101 + 4337 = 4438
- 149 + 4289 = 4438
- 167 + 4271 = 4438
Showing the first eight; more decompositions exist.
