Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80782, here are decompositions:
- 3 + 80779 = 80782
- 5 + 80777 = 80782
- 101 + 80681 = 80782
- 113 + 80669 = 80782
- 131 + 80651 = 80782
- 179 + 80603 = 80782
- 269 + 80513 = 80782
- 293 + 80489 = 80782
Showing the first eight; more decompositions exist.
