Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30646, here are decompositions:
- 3 + 30643 = 30646
- 53 + 30593 = 30646
- 89 + 30557 = 30646
- 107 + 30539 = 30646
- 137 + 30509 = 30646
- 149 + 30497 = 30646
- 179 + 30467 = 30646
- 197 + 30449 = 30646
Showing the first eight; more decompositions exist.
