Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87136, here are decompositions:
- 3 + 87133 = 87136
- 17 + 87119 = 87136
- 29 + 87107 = 87136
- 53 + 87083 = 87136
- 167 + 86969 = 87136
- 197 + 86939 = 87136
- 293 + 86843 = 87136
- 353 + 86783 = 87136
Showing the first eight; more decompositions exist.
