Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12178, here are decompositions:
- 17 + 12161 = 12178
- 29 + 12149 = 12178
- 59 + 12119 = 12178
- 71 + 12107 = 12178
- 107 + 12071 = 12178
- 137 + 12041 = 12178
- 167 + 12011 = 12178
- 191 + 11987 = 12178
Showing the first eight; more decompositions exist.
