Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26840, here are decompositions:
- 7 + 26833 = 26840
- 19 + 26821 = 26840
- 103 + 26737 = 26840
- 109 + 26731 = 26840
- 127 + 26713 = 26840
- 139 + 26701 = 26840
- 157 + 26683 = 26840
- 193 + 26647 = 26840
Showing the first eight; more decompositions exist.
