Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19844, here are decompositions:
- 3 + 19841 = 19844
- 31 + 19813 = 19844
- 43 + 19801 = 19844
- 67 + 19777 = 19844
- 127 + 19717 = 19844
- 157 + 19687 = 19844
- 163 + 19681 = 19844
- 241 + 19603 = 19844
Showing the first eight; more decompositions exist.
