Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45840, here are decompositions:
- 7 + 45833 = 45840
- 13 + 45827 = 45840
- 17 + 45823 = 45840
- 19 + 45821 = 45840
- 23 + 45817 = 45840
- 61 + 45779 = 45840
- 73 + 45767 = 45840
- 83 + 45757 = 45840
Showing the first eight; more decompositions exist.
