Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45920, here are decompositions:
- 67 + 45853 = 45920
- 79 + 45841 = 45920
- 97 + 45823 = 45920
- 103 + 45817 = 45920
- 157 + 45763 = 45920
- 163 + 45757 = 45920
- 223 + 45697 = 45920
- 229 + 45691 = 45920
Showing the first eight; more decompositions exist.
