Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7378, here are decompositions:
- 29 + 7349 = 7378
- 47 + 7331 = 7378
- 71 + 7307 = 7378
- 131 + 7247 = 7378
- 149 + 7229 = 7378
- 167 + 7211 = 7378
- 191 + 7187 = 7378
- 227 + 7151 = 7378
Showing the first eight; more decompositions exist.
