Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158318, here are decompositions:
- 109 + 158209 = 158318
- 157 + 158161 = 158318
- 241 + 158077 = 158318
- 271 + 158047 = 158318
- 367 + 157951 = 158318
- 421 + 157897 = 158318
- 487 + 157831 = 158318
- 547 + 157771 = 158318
Showing the first eight; more decompositions exist.
