Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33990, here are decompositions:
- 23 + 33967 = 33990
- 29 + 33961 = 33990
- 53 + 33937 = 33990
- 59 + 33931 = 33990
- 67 + 33923 = 33990
- 79 + 33911 = 33990
- 97 + 33893 = 33990
- 101 + 33889 = 33990
Showing the first eight; more decompositions exist.
