Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2184, here are decompositions:
- 5 + 2179 = 2184
- 23 + 2161 = 2184
- 31 + 2153 = 2184
- 41 + 2143 = 2184
- 43 + 2141 = 2184
- 47 + 2137 = 2184
- 53 + 2131 = 2184
- 71 + 2113 = 2184
Showing the first eight; more decompositions exist.
