Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80320, here are decompositions:
- 3 + 80317 = 80320
- 11 + 80309 = 80320
- 41 + 80279 = 80320
- 47 + 80273 = 80320
- 89 + 80231 = 80320
- 113 + 80207 = 80320
- 167 + 80153 = 80320
- 173 + 80147 = 80320
Showing the first eight; more decompositions exist.
