Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20754, here are decompositions:
- 5 + 20749 = 20754
- 7 + 20747 = 20754
- 11 + 20743 = 20754
- 23 + 20731 = 20754
- 37 + 20717 = 20754
- 47 + 20707 = 20754
- 61 + 20693 = 20754
- 73 + 20681 = 20754
Showing the first eight; more decompositions exist.
