Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20160, here are decompositions:
- 11 + 20149 = 20160
- 13 + 20147 = 20160
- 17 + 20143 = 20160
- 31 + 20129 = 20160
- 37 + 20123 = 20160
- 43 + 20117 = 20160
- 47 + 20113 = 20160
- 53 + 20107 = 20160
Showing the first eight; more decompositions exist.
