Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557938, here are decompositions:
- 17 + 33557921 = 33557938
- 47 + 33557891 = 33557938
- 59 + 33557879 = 33557938
- 101 + 33557837 = 33557938
- 131 + 33557807 = 33557938
- 149 + 33557789 = 33557938
- 257 + 33557681 = 33557938
- 311 + 33557627 = 33557938
Showing the first eight; more decompositions exist.
