Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26380, here are decompositions:
- 23 + 26357 = 26380
- 41 + 26339 = 26380
- 59 + 26321 = 26380
- 71 + 26309 = 26380
- 83 + 26297 = 26380
- 113 + 26267 = 26380
- 131 + 26249 = 26380
- 191 + 26189 = 26380
Showing the first eight; more decompositions exist.
