Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19994, here are decompositions:
- 3 + 19991 = 19994
- 31 + 19963 = 19994
- 67 + 19927 = 19994
- 103 + 19891 = 19994
- 127 + 19867 = 19994
- 151 + 19843 = 19994
- 181 + 19813 = 19994
- 193 + 19801 = 19994
Showing the first eight; more decompositions exist.
