Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30286, here are decompositions:
- 17 + 30269 = 30286
- 83 + 30203 = 30286
- 89 + 30197 = 30286
- 149 + 30137 = 30286
- 167 + 30119 = 30286
- 173 + 30113 = 30286
- 197 + 30089 = 30286
- 227 + 30059 = 30286
Showing the first eight; more decompositions exist.
