Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80380, here are decompositions:
- 11 + 80369 = 80380
- 17 + 80363 = 80380
- 71 + 80309 = 80380
- 101 + 80279 = 80380
- 107 + 80273 = 80380
- 149 + 80231 = 80380
- 173 + 80207 = 80380
- 227 + 80153 = 80380
Showing the first eight; more decompositions exist.
