Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45990, here are decompositions:
- 11 + 45979 = 45990
- 19 + 45971 = 45990
- 31 + 45959 = 45990
- 37 + 45953 = 45990
- 41 + 45949 = 45990
- 47 + 45943 = 45990
- 97 + 45893 = 45990
- 103 + 45887 = 45990
Showing the first eight; more decompositions exist.
