Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54400, here are decompositions:
- 23 + 54377 = 54400
- 29 + 54371 = 54400
- 53 + 54347 = 54400
- 89 + 54311 = 54400
- 107 + 54293 = 54400
- 113 + 54287 = 54400
- 131 + 54269 = 54400
- 149 + 54251 = 54400
Showing the first eight; more decompositions exist.
