Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80506, here are decompositions:
- 17 + 80489 = 80506
- 59 + 80447 = 80506
- 137 + 80369 = 80506
- 197 + 80309 = 80506
- 227 + 80279 = 80506
- 233 + 80273 = 80506
- 353 + 80153 = 80506
- 359 + 80147 = 80506
Showing the first eight; more decompositions exist.
