Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12184, here are decompositions:
- 23 + 12161 = 12184
- 41 + 12143 = 12184
- 71 + 12113 = 12184
- 83 + 12101 = 12184
- 113 + 12071 = 12184
- 173 + 12011 = 12184
- 197 + 11987 = 12184
- 251 + 11933 = 12184
Showing the first eight; more decompositions exist.
