Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28248, here are decompositions:
- 19 + 28229 = 28248
- 29 + 28219 = 28248
- 37 + 28211 = 28248
- 47 + 28201 = 28248
- 67 + 28181 = 28248
- 97 + 28151 = 28248
- 137 + 28111 = 28248
- 139 + 28109 = 28248
Showing the first eight; more decompositions exist.
