Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45668, here are decompositions:
- 37 + 45631 = 45668
- 79 + 45589 = 45668
- 127 + 45541 = 45668
- 229 + 45439 = 45668
- 241 + 45427 = 45668
- 307 + 45361 = 45668
- 331 + 45337 = 45668
- 349 + 45319 = 45668
Showing the first eight; more decompositions exist.
