Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9812, here are decompositions:
- 31 + 9781 = 9812
- 43 + 9769 = 9812
- 73 + 9739 = 9812
- 79 + 9733 = 9812
- 151 + 9661 = 9812
- 163 + 9649 = 9812
- 181 + 9631 = 9812
- 193 + 9619 = 9812
Showing the first eight; more decompositions exist.
