Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20036, here are decompositions:
- 7 + 20029 = 20036
- 13 + 20023 = 20036
- 43 + 19993 = 20036
- 73 + 19963 = 20036
- 109 + 19927 = 20036
- 193 + 19843 = 20036
- 223 + 19813 = 20036
- 277 + 19759 = 20036
Showing the first eight; more decompositions exist.
