Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472920, here are decompositions:
- 7 + 33472913 = 33472920
- 17 + 33472903 = 33472920
- 29 + 33472891 = 33472920
- 71 + 33472849 = 33472920
- 97 + 33472823 = 33472920
- 137 + 33472783 = 33472920
- 149 + 33472771 = 33472920
- 197 + 33472723 = 33472920
Showing the first eight; more decompositions exist.
