Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87160, here are decompositions:
- 11 + 87149 = 87160
- 41 + 87119 = 87160
- 53 + 87107 = 87160
- 89 + 87071 = 87160
- 149 + 87011 = 87160
- 167 + 86993 = 87160
- 179 + 86981 = 87160
- 191 + 86969 = 87160
Showing the first eight; more decompositions exist.
