Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159216, here are decompositions:
- 7 + 159209 = 159216
- 17 + 159199 = 159216
- 23 + 159193 = 159216
- 37 + 159179 = 159216
- 47 + 159169 = 159216
- 59 + 159157 = 159216
- 97 + 159119 = 159216
- 103 + 159113 = 159216
Showing the first eight; more decompositions exist.
