Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7250, here are decompositions:
- 3 + 7247 = 7250
- 7 + 7243 = 7250
- 13 + 7237 = 7250
- 31 + 7219 = 7250
- 37 + 7213 = 7250
- 43 + 7207 = 7250
- 73 + 7177 = 7250
- 181 + 7069 = 7250
Showing the first eight; more decompositions exist.
