Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45288, here are decompositions:
- 7 + 45281 = 45288
- 29 + 45259 = 45288
- 41 + 45247 = 45288
- 97 + 45191 = 45288
- 107 + 45181 = 45288
- 109 + 45179 = 45288
- 127 + 45161 = 45288
- 149 + 45139 = 45288
Showing the first eight; more decompositions exist.
