Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68820, here are decompositions:
- 7 + 68813 = 68820
- 29 + 68791 = 68820
- 43 + 68777 = 68820
- 53 + 68767 = 68820
- 71 + 68749 = 68820
- 83 + 68737 = 68820
- 107 + 68713 = 68820
- 109 + 68711 = 68820
Showing the first eight; more decompositions exist.
