Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529016, here are decompositions:
- 19 + 31528997 = 31529016
- 23 + 31528993 = 31529016
- 47 + 31528969 = 31529016
- 107 + 31528909 = 31529016
- 163 + 31528853 = 31529016
- 173 + 31528843 = 31529016
- 193 + 31528823 = 31529016
- 293 + 31528723 = 31529016
Showing the first eight; more decompositions exist.
