Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561840, here are decompositions:
- 23 + 33561817 = 33561840
- 41 + 33561799 = 33561840
- 61 + 33561779 = 33561840
- 71 + 33561769 = 33561840
- 73 + 33561767 = 33561840
- 89 + 33561751 = 33561840
- 97 + 33561743 = 33561840
- 167 + 33561673 = 33561840
Showing the first eight; more decompositions exist.
