Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7112, here are decompositions:
- 3 + 7109 = 7112
- 43 + 7069 = 7112
- 73 + 7039 = 7112
- 151 + 6961 = 7112
- 163 + 6949 = 7112
- 229 + 6883 = 7112
- 241 + 6871 = 7112
- 271 + 6841 = 7112
Showing the first eight; more decompositions exist.
