Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19964, here are decompositions:
- 3 + 19961 = 19964
- 37 + 19927 = 19964
- 73 + 19891 = 19964
- 97 + 19867 = 19964
- 103 + 19861 = 19964
- 151 + 19813 = 19964
- 163 + 19801 = 19964
- 211 + 19753 = 19964
Showing the first eight; more decompositions exist.
