Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87232, here are decompositions:
- 11 + 87221 = 87232
- 53 + 87179 = 87232
- 83 + 87149 = 87232
- 113 + 87119 = 87232
- 149 + 87083 = 87232
- 191 + 87041 = 87232
- 239 + 86993 = 87232
- 251 + 86981 = 87232
Showing the first eight; more decompositions exist.
