Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20924, here are decompositions:
- 3 + 20921 = 20924
- 37 + 20887 = 20924
- 67 + 20857 = 20924
- 151 + 20773 = 20924
- 181 + 20743 = 20924
- 193 + 20731 = 20924
- 283 + 20641 = 20924
- 313 + 20611 = 20924
Showing the first eight; more decompositions exist.
