Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72532, here are decompositions:
- 29 + 72503 = 72532
- 71 + 72461 = 72532
- 101 + 72431 = 72532
- 149 + 72383 = 72532
- 179 + 72353 = 72532
- 191 + 72341 = 72532
- 263 + 72269 = 72532
- 281 + 72251 = 72532
Showing the first eight; more decompositions exist.
