Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72026, here are decompositions:
- 7 + 72019 = 72026
- 43 + 71983 = 72026
- 79 + 71947 = 72026
- 109 + 71917 = 72026
- 127 + 71899 = 72026
- 139 + 71887 = 72026
- 307 + 71719 = 72026
- 313 + 71713 = 72026
Showing the first eight; more decompositions exist.
