Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28844, here are decompositions:
- 7 + 28837 = 28844
- 31 + 28813 = 28844
- 37 + 28807 = 28844
- 73 + 28771 = 28844
- 157 + 28687 = 28844
- 181 + 28663 = 28844
- 223 + 28621 = 28844
- 241 + 28603 = 28844
Showing the first eight; more decompositions exist.
