Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45280, here are decompositions:
- 17 + 45263 = 45280
- 47 + 45233 = 45280
- 83 + 45197 = 45280
- 89 + 45191 = 45280
- 101 + 45179 = 45280
- 149 + 45131 = 45280
- 197 + 45083 = 45280
- 227 + 45053 = 45280
Showing the first eight; more decompositions exist.
