Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12104, here are decompositions:
- 3 + 12101 = 12104
- 7 + 12097 = 12104
- 31 + 12073 = 12104
- 61 + 12043 = 12104
- 67 + 12037 = 12104
- 97 + 12007 = 12104
- 151 + 11953 = 12104
- 163 + 11941 = 12104
Showing the first eight; more decompositions exist.
