Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88638, here are decompositions:
- 29 + 88609 = 88638
- 31 + 88607 = 88638
- 47 + 88591 = 88638
- 139 + 88499 = 88638
- 167 + 88471 = 88638
- 211 + 88427 = 88638
- 227 + 88411 = 88638
- 241 + 88397 = 88638
Showing the first eight; more decompositions exist.
