Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12028, here are decompositions:
- 17 + 12011 = 12028
- 41 + 11987 = 12028
- 47 + 11981 = 12028
- 59 + 11969 = 12028
- 89 + 11939 = 12028
- 101 + 11927 = 12028
- 131 + 11897 = 12028
- 197 + 11831 = 12028
Showing the first eight; more decompositions exist.
