Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157618, here are decompositions:
- 47 + 157571 = 157618
- 59 + 157559 = 157618
- 191 + 157427 = 157618
- 269 + 157349 = 157618
- 311 + 157307 = 157618
- 347 + 157271 = 157618
- 359 + 157259 = 157618
- 389 + 157229 = 157618
Showing the first eight; more decompositions exist.
