Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7206, here are decompositions:
- 13 + 7193 = 7206
- 19 + 7187 = 7206
- 29 + 7177 = 7206
- 47 + 7159 = 7206
- 79 + 7127 = 7206
- 97 + 7109 = 7206
- 103 + 7103 = 7206
- 127 + 7079 = 7206
Showing the first eight; more decompositions exist.
