Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26820, here are decompositions:
- 7 + 26813 = 26820
- 19 + 26801 = 26820
- 37 + 26783 = 26820
- 43 + 26777 = 26820
- 61 + 26759 = 26820
- 83 + 26737 = 26820
- 89 + 26731 = 26820
- 97 + 26723 = 26820
Showing the first eight; more decompositions exist.
