Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561380, here are decompositions:
- 19 + 33561361 = 33561380
- 37 + 33561343 = 33561380
- 109 + 33561271 = 33561380
- 199 + 33561181 = 33561380
- 211 + 33561169 = 33561380
- 241 + 33561139 = 33561380
- 277 + 33561103 = 33561380
- 313 + 33561067 = 33561380
Showing the first eight; more decompositions exist.
