Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526942, here are decompositions:
- 3 + 31526939 = 31526942
- 43 + 31526899 = 31526942
- 61 + 31526881 = 31526942
- 79 + 31526863 = 31526942
- 151 + 31526791 = 31526942
- 193 + 31526749 = 31526942
- 211 + 31526731 = 31526942
- 229 + 31526713 = 31526942
Showing the first eight; more decompositions exist.
