Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526810, here are decompositions:
- 19 + 31526791 = 31526810
- 37 + 31526773 = 31526810
- 61 + 31526749 = 31526810
- 79 + 31526731 = 31526810
- 97 + 31526713 = 31526810
- 163 + 31526647 = 31526810
- 193 + 31526617 = 31526810
- 277 + 31526533 = 31526810
Showing the first eight; more decompositions exist.
