Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33120, here are decompositions:
- 7 + 33113 = 33120
- 13 + 33107 = 33120
- 29 + 33091 = 33120
- 37 + 33083 = 33120
- 47 + 33073 = 33120
- 67 + 33053 = 33120
- 71 + 33049 = 33120
- 83 + 33037 = 33120
Showing the first eight; more decompositions exist.
