Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28790, here are decompositions:
- 19 + 28771 = 28790
- 31 + 28759 = 28790
- 37 + 28753 = 28790
- 61 + 28729 = 28790
- 67 + 28723 = 28790
- 79 + 28711 = 28790
- 103 + 28687 = 28790
- 127 + 28663 = 28790
Showing the first eight; more decompositions exist.
