Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45540, here are decompositions:
- 7 + 45533 = 45540
- 17 + 45523 = 45540
- 37 + 45503 = 45540
- 43 + 45497 = 45540
- 59 + 45481 = 45540
- 101 + 45439 = 45540
- 107 + 45433 = 45540
- 113 + 45427 = 45540
Showing the first eight; more decompositions exist.
