Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87836, here are decompositions:
- 3 + 87833 = 87836
- 43 + 87793 = 87836
- 97 + 87739 = 87836
- 139 + 87697 = 87836
- 157 + 87679 = 87836
- 193 + 87643 = 87836
- 223 + 87613 = 87836
- 277 + 87559 = 87836
Showing the first eight; more decompositions exist.
