Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80002, here are decompositions:
- 3 + 79999 = 80002
- 5 + 79997 = 80002
- 23 + 79979 = 80002
- 29 + 79973 = 80002
- 59 + 79943 = 80002
- 101 + 79901 = 80002
- 113 + 79889 = 80002
- 173 + 79829 = 80002
Showing the first eight; more decompositions exist.
