Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72250, here are decompositions:
- 23 + 72227 = 72250
- 29 + 72221 = 72250
- 83 + 72167 = 72250
- 89 + 72161 = 72250
- 149 + 72101 = 72250
- 173 + 72077 = 72250
- 197 + 72053 = 72250
- 251 + 71999 = 72250
Showing the first eight; more decompositions exist.
