Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53456, here are decompositions:
- 3 + 53453 = 53456
- 19 + 53437 = 53456
- 37 + 53419 = 53456
- 79 + 53377 = 53456
- 97 + 53359 = 53456
- 103 + 53353 = 53456
- 157 + 53299 = 53456
- 223 + 53233 = 53456
Showing the first eight; more decompositions exist.
