Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7148, here are decompositions:
- 19 + 7129 = 7148
- 79 + 7069 = 7148
- 109 + 7039 = 7148
- 151 + 6997 = 7148
- 157 + 6991 = 7148
- 181 + 6967 = 7148
- 199 + 6949 = 7148
- 241 + 6907 = 7148
Showing the first eight; more decompositions exist.
