Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542640, here are decompositions:
- 23 + 33542617 = 33542640
- 29 + 33542611 = 33542640
- 37 + 33542603 = 33542640
- 67 + 33542573 = 33542640
- 73 + 33542567 = 33542640
- 83 + 33542557 = 33542640
- 101 + 33542539 = 33542640
- 149 + 33542491 = 33542640
Showing the first eight; more decompositions exist.
