Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79818, here are decompositions:
- 5 + 79813 = 79818
- 7 + 79811 = 79818
- 17 + 79801 = 79818
- 41 + 79777 = 79818
- 61 + 79757 = 79818
- 127 + 79691 = 79818
- 131 + 79687 = 79818
- 149 + 79669 = 79818
Showing the first eight; more decompositions exist.
