Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12144, here are decompositions:
- 31 + 12113 = 12144
- 37 + 12107 = 12144
- 43 + 12101 = 12144
- 47 + 12097 = 12144
- 71 + 12073 = 12144
- 73 + 12071 = 12144
- 101 + 12043 = 12144
- 103 + 12041 = 12144
Showing the first eight; more decompositions exist.
