Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28444, here are decompositions:
- 5 + 28439 = 28444
- 11 + 28433 = 28444
- 41 + 28403 = 28444
- 137 + 28307 = 28444
- 167 + 28277 = 28444
- 233 + 28211 = 28444
- 263 + 28181 = 28444
- 281 + 28163 = 28444
Showing the first eight; more decompositions exist.
