Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159960, here are decompositions:
- 23 + 159937 = 159960
- 29 + 159931 = 159960
- 61 + 159899 = 159960
- 89 + 159871 = 159960
- 103 + 159857 = 159960
- 107 + 159853 = 159960
- 127 + 159833 = 159960
- 149 + 159811 = 159960
Showing the first eight; more decompositions exist.
