Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30154, here are decompositions:
- 17 + 30137 = 30154
- 41 + 30113 = 30154
- 83 + 30071 = 30154
- 107 + 30047 = 30154
- 227 + 29927 = 30154
- 233 + 29921 = 30154
- 281 + 29873 = 30154
- 317 + 29837 = 30154
Showing the first eight; more decompositions exist.
