Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12118, here are decompositions:
- 5 + 12113 = 12118
- 11 + 12107 = 12118
- 17 + 12101 = 12118
- 47 + 12071 = 12118
- 107 + 12011 = 12118
- 131 + 11987 = 12118
- 137 + 11981 = 12118
- 149 + 11969 = 12118
Showing the first eight; more decompositions exist.
