Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63990, here are decompositions:
- 13 + 63977 = 63990
- 41 + 63949 = 63990
- 61 + 63929 = 63990
- 83 + 63907 = 63990
- 89 + 63901 = 63990
- 127 + 63863 = 63990
- 137 + 63853 = 63990
- 149 + 63841 = 63990
Showing the first eight; more decompositions exist.
