Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527090, here are decompositions:
- 13 + 31527077 = 31527090
- 43 + 31527047 = 31527090
- 73 + 31527017 = 31527090
- 79 + 31527011 = 31527090
- 137 + 31526953 = 31527090
- 149 + 31526941 = 31527090
- 151 + 31526939 = 31527090
- 163 + 31526927 = 31527090
Showing the first eight; more decompositions exist.
