Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159744, here are decompositions:
- 5 + 159739 = 159744
- 7 + 159737 = 159744
- 23 + 159721 = 159744
- 37 + 159707 = 159744
- 43 + 159701 = 159744
- 47 + 159697 = 159744
- 61 + 159683 = 159744
- 71 + 159673 = 159744
Showing the first eight; more decompositions exist.
