Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5394, here are decompositions:
- 7 + 5387 = 5394
- 13 + 5381 = 5394
- 43 + 5351 = 5394
- 47 + 5347 = 5394
- 61 + 5333 = 5394
- 71 + 5323 = 5394
- 97 + 5297 = 5394
- 113 + 5281 = 5394
Showing the first eight; more decompositions exist.
