Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79966, here are decompositions:
- 23 + 79943 = 79966
- 59 + 79907 = 79966
- 137 + 79829 = 79966
- 149 + 79817 = 79966
- 197 + 79769 = 79966
- 269 + 79697 = 79966
- 353 + 79613 = 79966
- 569 + 79397 = 79966
Showing the first eight; more decompositions exist.
