Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80026, here are decompositions:
- 5 + 80021 = 80026
- 29 + 79997 = 80026
- 47 + 79979 = 80026
- 53 + 79973 = 80026
- 59 + 79967 = 80026
- 83 + 79943 = 80026
- 137 + 79889 = 80026
- 179 + 79847 = 80026
Showing the first eight; more decompositions exist.
