Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7248, here are decompositions:
- 5 + 7243 = 7248
- 11 + 7237 = 7248
- 19 + 7229 = 7248
- 29 + 7219 = 7248
- 37 + 7211 = 7248
- 41 + 7207 = 7248
- 61 + 7187 = 7248
- 71 + 7177 = 7248
Showing the first eight; more decompositions exist.
