Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26400, here are decompositions:
- 7 + 26393 = 26400
- 13 + 26387 = 26400
- 29 + 26371 = 26400
- 43 + 26357 = 26400
- 53 + 26347 = 26400
- 61 + 26339 = 26400
- 79 + 26321 = 26400
- 83 + 26317 = 26400
Showing the first eight; more decompositions exist.
