Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28832, here are decompositions:
- 19 + 28813 = 28832
- 43 + 28789 = 28832
- 61 + 28771 = 28832
- 73 + 28759 = 28832
- 79 + 28753 = 28832
- 103 + 28729 = 28832
- 109 + 28723 = 28832
- 163 + 28669 = 28832
Showing the first eight; more decompositions exist.
