Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28308, here are decompositions:
- 11 + 28297 = 28308
- 19 + 28289 = 28308
- 29 + 28279 = 28308
- 31 + 28277 = 28308
- 79 + 28229 = 28308
- 89 + 28219 = 28308
- 97 + 28211 = 28308
- 107 + 28201 = 28308
Showing the first eight; more decompositions exist.
