Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21074, here are decompositions:
- 7 + 21067 = 21074
- 13 + 21061 = 21074
- 43 + 21031 = 21074
- 61 + 21013 = 21074
- 73 + 21001 = 21074
- 127 + 20947 = 21074
- 331 + 20743 = 21074
- 367 + 20707 = 21074
Showing the first eight; more decompositions exist.
