Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162888, here are decompositions:
- 7 + 162881 = 162888
- 29 + 162859 = 162888
- 41 + 162847 = 162888
- 59 + 162829 = 162888
- 67 + 162821 = 162888
- 97 + 162791 = 162888
- 101 + 162787 = 162888
- 109 + 162779 = 162888
Showing the first eight; more decompositions exist.
