Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521940, here are decompositions:
- 7 + 33521933 = 33521940
- 13 + 33521927 = 33521940
- 19 + 33521921 = 33521940
- 37 + 33521903 = 33521940
- 47 + 33521893 = 33521940
- 79 + 33521861 = 33521940
- 97 + 33521843 = 33521940
- 113 + 33521827 = 33521940
Showing the first eight; more decompositions exist.
