Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527834, here are decompositions:
- 5 + 31527829 = 31527834
- 7 + 31527827 = 31527834
- 17 + 31527817 = 31527834
- 47 + 31527787 = 31527834
- 53 + 31527781 = 31527834
- 131 + 31527703 = 31527834
- 137 + 31527697 = 31527834
- 157 + 31527677 = 31527834
Showing the first eight; more decompositions exist.
