Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72310, here are decompositions:
- 3 + 72307 = 72310
- 23 + 72287 = 72310
- 41 + 72269 = 72310
- 59 + 72251 = 72310
- 83 + 72227 = 72310
- 89 + 72221 = 72310
- 137 + 72173 = 72310
- 149 + 72161 = 72310
Showing the first eight; more decompositions exist.
