Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72108, here are decompositions:
- 5 + 72103 = 72108
- 7 + 72101 = 72108
- 17 + 72091 = 72108
- 19 + 72089 = 72108
- 31 + 72077 = 72108
- 61 + 72047 = 72108
- 89 + 72019 = 72108
- 109 + 71999 = 72108
Showing the first eight; more decompositions exist.
