Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7256, here are decompositions:
- 3 + 7253 = 7256
- 13 + 7243 = 7256
- 19 + 7237 = 7256
- 37 + 7219 = 7256
- 43 + 7213 = 7256
- 79 + 7177 = 7256
- 97 + 7159 = 7256
- 127 + 7129 = 7256
Showing the first eight; more decompositions exist.
