Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45490, here are decompositions:
- 101 + 45389 = 45490
- 113 + 45377 = 45490
- 149 + 45341 = 45490
- 173 + 45317 = 45490
- 197 + 45293 = 45490
- 227 + 45263 = 45490
- 257 + 45233 = 45490
- 293 + 45197 = 45490
Showing the first eight; more decompositions exist.
