Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528938, here are decompositions:
- 29 + 31528909 = 31528938
- 97 + 31528841 = 31528938
- 107 + 31528831 = 31528938
- 127 + 31528811 = 31528938
- 131 + 31528807 = 31528938
- 137 + 31528801 = 31528938
- 197 + 31528741 = 31528938
- 241 + 31528697 = 31528938
Showing the first eight; more decompositions exist.
