Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45040, here are decompositions:
- 53 + 44987 = 45040
- 101 + 44939 = 45040
- 113 + 44927 = 45040
- 131 + 44909 = 45040
- 173 + 44867 = 45040
- 197 + 44843 = 45040
- 251 + 44789 = 45040
- 263 + 44777 = 45040
Showing the first eight; more decompositions exist.
