Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87184, here are decompositions:
- 3 + 87181 = 87184
- 5 + 87179 = 87184
- 101 + 87083 = 87184
- 113 + 87071 = 87184
- 173 + 87011 = 87184
- 191 + 86993 = 87184
- 233 + 86951 = 87184
- 257 + 86927 = 87184
Showing the first eight; more decompositions exist.
