Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7418, here are decompositions:
- 7 + 7411 = 7418
- 67 + 7351 = 7418
- 97 + 7321 = 7418
- 109 + 7309 = 7418
- 181 + 7237 = 7418
- 199 + 7219 = 7418
- 211 + 7207 = 7418
- 241 + 7177 = 7418
Showing the first eight; more decompositions exist.
