Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12100, here are decompositions:
- 3 + 12097 = 12100
- 29 + 12071 = 12100
- 59 + 12041 = 12100
- 89 + 12011 = 12100
- 113 + 11987 = 12100
- 131 + 11969 = 12100
- 167 + 11933 = 12100
- 173 + 11927 = 12100
Showing the first eight; more decompositions exist.
