Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20994, here are decompositions:
- 11 + 20983 = 20994
- 13 + 20981 = 20994
- 31 + 20963 = 20994
- 47 + 20947 = 20994
- 73 + 20921 = 20994
- 97 + 20897 = 20994
- 107 + 20887 = 20994
- 137 + 20857 = 20994
Showing the first eight; more decompositions exist.
