Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30586, here are decompositions:
- 29 + 30557 = 30586
- 47 + 30539 = 30586
- 89 + 30497 = 30586
- 137 + 30449 = 30586
- 197 + 30389 = 30586
- 239 + 30347 = 30586
- 263 + 30323 = 30586
- 293 + 30293 = 30586
Showing the first eight; more decompositions exist.
