Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526930, here are decompositions:
- 3 + 31526927 = 31526930
- 31 + 31526899 = 31526930
- 37 + 31526893 = 31526930
- 67 + 31526863 = 31526930
- 139 + 31526791 = 31526930
- 157 + 31526773 = 31526930
- 181 + 31526749 = 31526930
- 199 + 31526731 = 31526930
Showing the first eight; more decompositions exist.
