Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15212, here are decompositions:
- 13 + 15199 = 15212
- 19 + 15193 = 15212
- 73 + 15139 = 15212
- 139 + 15073 = 15212
- 151 + 15061 = 15212
- 181 + 15031 = 15212
- 199 + 15013 = 15212
- 229 + 14983 = 15212
Showing the first eight; more decompositions exist.
