Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526894, here are decompositions:
- 13 + 31526881 = 31526894
- 31 + 31526863 = 31526894
- 103 + 31526791 = 31526894
- 163 + 31526731 = 31526894
- 181 + 31526713 = 31526894
- 277 + 31526617 = 31526894
- 331 + 31526563 = 31526894
- 367 + 31526527 = 31526894
Showing the first eight; more decompositions exist.
