Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163558, here are decompositions:
- 41 + 163517 = 163558
- 71 + 163487 = 163558
- 89 + 163469 = 163558
- 149 + 163409 = 163558
- 191 + 163367 = 163558
- 251 + 163307 = 163558
- 347 + 163211 = 163558
- 359 + 163199 = 163558
Showing the first eight; more decompositions exist.
