Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527078, here are decompositions:
- 31 + 31527047 = 31527078
- 61 + 31527017 = 31527078
- 67 + 31527011 = 31527078
- 137 + 31526941 = 31527078
- 139 + 31526939 = 31527078
- 151 + 31526927 = 31527078
- 157 + 31526921 = 31527078
- 179 + 31526899 = 31527078
Showing the first eight; more decompositions exist.
