Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30800, here are decompositions:
- 19 + 30781 = 30800
- 37 + 30763 = 30800
- 43 + 30757 = 30800
- 73 + 30727 = 30800
- 97 + 30703 = 30800
- 103 + 30697 = 30800
- 139 + 30661 = 30800
- 151 + 30649 = 30800
Showing the first eight; more decompositions exist.
