Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33550920, here are decompositions:
- 71 + 33550849 = 33550920
- 89 + 33550831 = 33550920
- 163 + 33550757 = 33550920
- 191 + 33550729 = 33550920
- 197 + 33550723 = 33550920
- 229 + 33550691 = 33550920
- 233 + 33550687 = 33550920
- 257 + 33550663 = 33550920
Showing the first eight; more decompositions exist.
