Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72364, here are decompositions:
- 11 + 72353 = 72364
- 23 + 72341 = 72364
- 113 + 72251 = 72364
- 137 + 72227 = 72364
- 191 + 72173 = 72364
- 197 + 72167 = 72364
- 263 + 72101 = 72364
- 311 + 72053 = 72364
Showing the first eight; more decompositions exist.
