Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88888, here are decompositions:
- 5 + 88883 = 88888
- 71 + 88817 = 88888
- 89 + 88799 = 88888
- 167 + 88721 = 88888
- 227 + 88661 = 88888
- 281 + 88607 = 88888
- 389 + 88499 = 88888
- 419 + 88469 = 88888
Showing the first eight; more decompositions exist.
