Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72392, here are decompositions:
- 13 + 72379 = 72392
- 79 + 72313 = 72392
- 139 + 72253 = 72392
- 163 + 72229 = 72392
- 181 + 72211 = 72392
- 223 + 72169 = 72392
- 283 + 72109 = 72392
- 349 + 72043 = 72392
Showing the first eight; more decompositions exist.
