Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527072, here are decompositions:
- 61 + 31527011 = 31527072
- 131 + 31526941 = 31527072
- 151 + 31526921 = 31527072
- 173 + 31526899 = 31527072
- 179 + 31526893 = 31527072
- 191 + 31526881 = 31527072
- 193 + 31526879 = 31527072
- 263 + 31526809 = 31527072
Showing the first eight; more decompositions exist.
