Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19824, here are decompositions:
- 5 + 19819 = 19824
- 11 + 19813 = 19824
- 23 + 19801 = 19824
- 31 + 19793 = 19824
- 47 + 19777 = 19824
- 61 + 19763 = 19824
- 71 + 19753 = 19824
- 73 + 19751 = 19824
Showing the first eight; more decompositions exist.
