Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79824, here are decompositions:
- 7 + 79817 = 79824
- 11 + 79813 = 79824
- 13 + 79811 = 79824
- 23 + 79801 = 79824
- 47 + 79777 = 79824
- 67 + 79757 = 79824
- 127 + 79697 = 79824
- 131 + 79693 = 79824
Showing the first eight; more decompositions exist.
