Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87452, here are decompositions:
- 19 + 87433 = 87452
- 31 + 87421 = 87452
- 139 + 87313 = 87452
- 199 + 87253 = 87452
- 229 + 87223 = 87452
- 241 + 87211 = 87452
- 271 + 87181 = 87452
- 331 + 87121 = 87452
Showing the first eight; more decompositions exist.
