Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5432, here are decompositions:
- 13 + 5419 = 5432
- 19 + 5413 = 5432
- 109 + 5323 = 5432
- 151 + 5281 = 5432
- 199 + 5233 = 5432
- 223 + 5209 = 5432
- 313 + 5119 = 5432
- 331 + 5101 = 5432
Showing the first eight; more decompositions exist.
