Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157648, here are decompositions:
- 11 + 157637 = 157648
- 89 + 157559 = 157648
- 191 + 157457 = 157648
- 389 + 157259 = 157648
- 401 + 157247 = 157648
- 419 + 157229 = 157648
- 431 + 157217 = 157648
- 467 + 157181 = 157648
Showing the first eight; more decompositions exist.
