Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49920, here are decompositions:
- 29 + 49891 = 49920
- 43 + 49877 = 49920
- 67 + 49853 = 49920
- 89 + 49831 = 49920
- 97 + 49823 = 49920
- 109 + 49811 = 49920
- 113 + 49807 = 49920
- 131 + 49789 = 49920
Showing the first eight; more decompositions exist.
