Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82144, here are decompositions:
- 3 + 82141 = 82144
- 5 + 82139 = 82144
- 71 + 82073 = 82144
- 107 + 82037 = 82144
- 113 + 82031 = 82144
- 131 + 82013 = 82144
- 137 + 82007 = 82144
- 173 + 81971 = 82144
Showing the first eight; more decompositions exist.
