Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20762, here are decompositions:
- 3 + 20759 = 20762
- 13 + 20749 = 20762
- 19 + 20743 = 20762
- 31 + 20731 = 20762
- 43 + 20719 = 20762
- 151 + 20611 = 20762
- 163 + 20599 = 20762
- 199 + 20563 = 20762
Showing the first eight; more decompositions exist.
