Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5406, here are decompositions:
- 7 + 5399 = 5406
- 13 + 5393 = 5406
- 19 + 5387 = 5406
- 59 + 5347 = 5406
- 73 + 5333 = 5406
- 83 + 5323 = 5406
- 97 + 5309 = 5406
- 103 + 5303 = 5406
Showing the first eight; more decompositions exist.
