Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509920, here are decompositions:
- 29 + 33509891 = 33509920
- 107 + 33509813 = 33509920
- 137 + 33509783 = 33509920
- 179 + 33509741 = 33509920
- 239 + 33509681 = 33509920
- 317 + 33509603 = 33509920
- 347 + 33509573 = 33509920
- 359 + 33509561 = 33509920
Showing the first eight; more decompositions exist.
