Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 957720, here are decompositions:
- 11 + 957709 = 957720
- 17 + 957703 = 957720
- 19 + 957701 = 957720
- 61 + 957659 = 957720
- 79 + 957641 = 957720
- 109 + 957611 = 957720
- 157 + 957563 = 957720
- 163 + 957557 = 957720
Showing the first eight; more decompositions exist.
