Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33180, here are decompositions:
- 19 + 33161 = 33180
- 29 + 33151 = 33180
- 31 + 33149 = 33180
- 61 + 33119 = 33180
- 67 + 33113 = 33180
- 73 + 33107 = 33180
- 89 + 33091 = 33180
- 97 + 33083 = 33180
Showing the first eight; more decompositions exist.
