Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7158, here are decompositions:
- 7 + 7151 = 7158
- 29 + 7129 = 7158
- 31 + 7127 = 7158
- 37 + 7121 = 7158
- 79 + 7079 = 7158
- 89 + 7069 = 7158
- 101 + 7057 = 7158
- 131 + 7027 = 7158
Showing the first eight; more decompositions exist.
