Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72344, here are decompositions:
- 3 + 72341 = 72344
- 7 + 72337 = 72344
- 31 + 72313 = 72344
- 37 + 72307 = 72344
- 67 + 72277 = 72344
- 73 + 72271 = 72344
- 241 + 72103 = 72344
- 271 + 72073 = 72344
Showing the first eight; more decompositions exist.
