Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528932, here are decompositions:
- 23 + 31528909 = 31528932
- 79 + 31528853 = 31528932
- 89 + 31528843 = 31528932
- 101 + 31528831 = 31528932
- 109 + 31528823 = 31528932
- 131 + 31528801 = 31528932
- 181 + 31528751 = 31528932
- 191 + 31528741 = 31528932
Showing the first eight; more decompositions exist.
