Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79918, here are decompositions:
- 11 + 79907 = 79918
- 17 + 79901 = 79918
- 29 + 79889 = 79918
- 71 + 79847 = 79918
- 89 + 79829 = 79918
- 101 + 79817 = 79918
- 107 + 79811 = 79918
- 149 + 79769 = 79918
Showing the first eight; more decompositions exist.
