Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7268, here are decompositions:
- 31 + 7237 = 7268
- 61 + 7207 = 7268
- 109 + 7159 = 7268
- 139 + 7129 = 7268
- 199 + 7069 = 7268
- 211 + 7057 = 7268
- 229 + 7039 = 7268
- 241 + 7027 = 7268
Showing the first eight; more decompositions exist.
