Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527030, here are decompositions:
- 13 + 31527017 = 31527030
- 19 + 31527011 = 31527030
- 89 + 31526941 = 31527030
- 103 + 31526927 = 31527030
- 109 + 31526921 = 31527030
- 127 + 31526903 = 31527030
- 131 + 31526899 = 31527030
- 137 + 31526893 = 31527030
Showing the first eight; more decompositions exist.
