Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561220, here are decompositions:
- 23 + 33561197 = 33561220
- 29 + 33561191 = 33561220
- 47 + 33561173 = 33561220
- 59 + 33561161 = 33561220
- 131 + 33561089 = 33561220
- 167 + 33561053 = 33561220
- 197 + 33561023 = 33561220
- 269 + 33560951 = 33561220
Showing the first eight; more decompositions exist.
