Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72452, here are decompositions:
- 31 + 72421 = 72452
- 73 + 72379 = 72452
- 139 + 72313 = 72452
- 181 + 72271 = 72452
- 199 + 72253 = 72452
- 223 + 72229 = 72452
- 229 + 72223 = 72452
- 241 + 72211 = 72452
Showing the first eight; more decompositions exist.
