Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45820, here are decompositions:
- 3 + 45817 = 45820
- 41 + 45779 = 45820
- 53 + 45767 = 45820
- 83 + 45737 = 45820
- 113 + 45707 = 45820
- 179 + 45641 = 45820
- 233 + 45587 = 45820
- 251 + 45569 = 45820
Showing the first eight; more decompositions exist.
