Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162558, here are decompositions:
- 5 + 162553 = 162558
- 29 + 162529 = 162558
- 31 + 162527 = 162558
- 41 + 162517 = 162558
- 59 + 162499 = 162558
- 101 + 162457 = 162558
- 107 + 162451 = 162558
- 139 + 162419 = 162558
Showing the first eight; more decompositions exist.
