Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20710, here are decompositions:
- 3 + 20707 = 20710
- 17 + 20693 = 20710
- 29 + 20681 = 20710
- 47 + 20663 = 20710
- 71 + 20639 = 20710
- 83 + 20627 = 20710
- 167 + 20543 = 20710
- 227 + 20483 = 20710
Showing the first eight; more decompositions exist.
