Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184, here are decompositions:
- 3 + 181 = 184
- 5 + 179 = 184
- 11 + 173 = 184
- 17 + 167 = 184
- 47 + 137 = 184
- 53 + 131 = 184
- 71 + 113 = 184
- 83 + 101 = 184
Showing the first eight; more decompositions exist.
