Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63920, here are decompositions:
- 7 + 63913 = 63920
- 13 + 63907 = 63920
- 19 + 63901 = 63920
- 67 + 63853 = 63920
- 79 + 63841 = 63920
- 97 + 63823 = 63920
- 127 + 63793 = 63920
- 139 + 63781 = 63920
Showing the first eight; more decompositions exist.
