Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87824, here are decompositions:
- 13 + 87811 = 87824
- 31 + 87793 = 87824
- 73 + 87751 = 87824
- 103 + 87721 = 87824
- 127 + 87697 = 87824
- 181 + 87643 = 87824
- 193 + 87631 = 87824
- 211 + 87613 = 87824
Showing the first eight; more decompositions exist.
