Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87208, here are decompositions:
- 29 + 87179 = 87208
- 59 + 87149 = 87208
- 89 + 87119 = 87208
- 101 + 87107 = 87208
- 137 + 87071 = 87208
- 167 + 87041 = 87208
- 197 + 87011 = 87208
- 227 + 86981 = 87208
Showing the first eight; more decompositions exist.
