Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527012, here are decompositions:
- 59 + 31526953 = 31527012
- 71 + 31526941 = 31527012
- 73 + 31526939 = 31527012
- 109 + 31526903 = 31527012
- 113 + 31526899 = 31527012
- 131 + 31526881 = 31527012
- 149 + 31526863 = 31527012
- 193 + 31526819 = 31527012
Showing the first eight; more decompositions exist.
