Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72372, here are decompositions:
- 5 + 72367 = 72372
- 19 + 72353 = 72372
- 31 + 72341 = 72372
- 59 + 72313 = 72372
- 101 + 72271 = 72372
- 103 + 72269 = 72372
- 149 + 72223 = 72372
- 151 + 72221 = 72372
Showing the first eight; more decompositions exist.
