Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7124, here are decompositions:
- 3 + 7121 = 7124
- 67 + 7057 = 7124
- 97 + 7027 = 7124
- 127 + 6997 = 7124
- 157 + 6967 = 7124
- 163 + 6961 = 7124
- 241 + 6883 = 7124
- 283 + 6841 = 7124
Showing the first eight; more decompositions exist.
