Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45220, here are decompositions:
- 23 + 45197 = 45220
- 29 + 45191 = 45220
- 41 + 45179 = 45220
- 59 + 45161 = 45220
- 83 + 45137 = 45220
- 89 + 45131 = 45220
- 101 + 45119 = 45220
- 137 + 45083 = 45220
Showing the first eight; more decompositions exist.
