Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527100, here are decompositions:
- 23 + 31527077 = 31527100
- 53 + 31527047 = 31527100
- 83 + 31527017 = 31527100
- 89 + 31527011 = 31527100
- 173 + 31526927 = 31527100
- 179 + 31526921 = 31527100
- 197 + 31526903 = 31527100
- 281 + 31526819 = 31527100
Showing the first eight; more decompositions exist.
