Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28330, here are decompositions:
- 11 + 28319 = 28330
- 23 + 28307 = 28330
- 41 + 28289 = 28330
- 47 + 28283 = 28330
- 53 + 28277 = 28330
- 101 + 28229 = 28330
- 149 + 28181 = 28330
- 167 + 28163 = 28330
Showing the first eight; more decompositions exist.
