Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72968, here are decompositions:
- 19 + 72949 = 72968
- 31 + 72937 = 72968
- 37 + 72931 = 72968
- 61 + 72907 = 72968
- 67 + 72901 = 72968
- 79 + 72889 = 72968
- 97 + 72871 = 72968
- 109 + 72859 = 72968
Showing the first eight; more decompositions exist.
