Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87828, here are decompositions:
- 17 + 87811 = 87828
- 31 + 87797 = 87828
- 61 + 87767 = 87828
- 89 + 87739 = 87828
- 107 + 87721 = 87828
- 109 + 87719 = 87828
- 127 + 87701 = 87828
- 131 + 87697 = 87828
Showing the first eight; more decompositions exist.
