Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72252, here are decompositions:
- 23 + 72229 = 72252
- 29 + 72223 = 72252
- 31 + 72221 = 72252
- 41 + 72211 = 72252
- 79 + 72173 = 72252
- 83 + 72169 = 72252
- 113 + 72139 = 72252
- 149 + 72103 = 72252
Showing the first eight; more decompositions exist.
