Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20752, here are decompositions:
- 3 + 20749 = 20752
- 5 + 20747 = 20752
- 59 + 20693 = 20752
- 71 + 20681 = 20752
- 89 + 20663 = 20752
- 113 + 20639 = 20752
- 269 + 20483 = 20752
- 311 + 20441 = 20752
Showing the first eight; more decompositions exist.
