Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12130, here are decompositions:
- 11 + 12119 = 12130
- 17 + 12113 = 12130
- 23 + 12107 = 12130
- 29 + 12101 = 12130
- 59 + 12071 = 12130
- 89 + 12041 = 12130
- 149 + 11981 = 12130
- 191 + 11939 = 12130
Showing the first eight; more decompositions exist.
