Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26842, here are decompositions:
- 3 + 26839 = 26842
- 29 + 26813 = 26842
- 41 + 26801 = 26842
- 59 + 26783 = 26842
- 83 + 26759 = 26842
- 113 + 26729 = 26842
- 131 + 26711 = 26842
- 149 + 26693 = 26842
Showing the first eight; more decompositions exist.
