Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12120, here are decompositions:
- 7 + 12113 = 12120
- 11 + 12109 = 12120
- 13 + 12107 = 12120
- 19 + 12101 = 12120
- 23 + 12097 = 12120
- 47 + 12073 = 12120
- 71 + 12049 = 12120
- 79 + 12041 = 12120
Showing the first eight; more decompositions exist.
