Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159664, here are decompositions:
- 41 + 159623 = 159664
- 47 + 159617 = 159664
- 101 + 159563 = 159664
- 173 + 159491 = 159664
- 191 + 159473 = 159664
- 227 + 159437 = 159664
- 233 + 159431 = 159664
- 257 + 159407 = 159664
Showing the first eight; more decompositions exist.
