Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625728, here are decompositions:
- 5 + 33625723 = 33625728
- 47 + 33625681 = 33625728
- 61 + 33625667 = 33625728
- 67 + 33625661 = 33625728
- 127 + 33625601 = 33625728
- 137 + 33625591 = 33625728
- 167 + 33625561 = 33625728
- 181 + 33625547 = 33625728
Showing the first eight; more decompositions exist.
