Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26720, here are decompositions:
- 3 + 26717 = 26720
- 7 + 26713 = 26720
- 19 + 26701 = 26720
- 37 + 26683 = 26720
- 73 + 26647 = 26720
- 79 + 26641 = 26720
- 163 + 26557 = 26720
- 181 + 26539 = 26720
Showing the first eight; more decompositions exist.
