Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7172, here are decompositions:
- 13 + 7159 = 7172
- 43 + 7129 = 7172
- 103 + 7069 = 7172
- 181 + 6991 = 7172
- 211 + 6961 = 7172
- 223 + 6949 = 7172
- 331 + 6841 = 7172
- 349 + 6823 = 7172
Showing the first eight; more decompositions exist.
