Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 942816, here are decompositions:
- 5 + 942811 = 942816
- 29 + 942787 = 942816
- 37 + 942779 = 942816
- 53 + 942763 = 942816
- 67 + 942749 = 942816
- 89 + 942727 = 942816
- 97 + 942719 = 942816
- 107 + 942709 = 942816
Showing the first eight; more decompositions exist.
