Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63968, here are decompositions:
- 19 + 63949 = 63968
- 61 + 63907 = 63968
- 67 + 63901 = 63968
- 127 + 63841 = 63968
- 241 + 63727 = 63968
- 271 + 63697 = 63968
- 277 + 63691 = 63968
- 367 + 63601 = 63968
Showing the first eight; more decompositions exist.
