Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72370, here are decompositions:
- 3 + 72367 = 72370
- 17 + 72353 = 72370
- 29 + 72341 = 72370
- 83 + 72287 = 72370
- 101 + 72269 = 72370
- 149 + 72221 = 72370
- 197 + 72173 = 72370
- 269 + 72101 = 72370
Showing the first eight; more decompositions exist.
