Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72068, here are decompositions:
- 37 + 72031 = 72068
- 97 + 71971 = 72068
- 127 + 71941 = 72068
- 151 + 71917 = 72068
- 181 + 71887 = 72068
- 307 + 71761 = 72068
- 349 + 71719 = 72068
- 397 + 71671 = 72068
Showing the first eight; more decompositions exist.
