Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83280, here are decompositions:
- 7 + 83273 = 83280
- 11 + 83269 = 83280
- 13 + 83267 = 83280
- 23 + 83257 = 83280
- 37 + 83243 = 83280
- 47 + 83233 = 83280
- 53 + 83227 = 83280
- 59 + 83221 = 83280
Showing the first eight; more decompositions exist.
