Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88666, here are decompositions:
- 3 + 88663 = 88666
- 5 + 88661 = 88666
- 23 + 88643 = 88666
- 59 + 88607 = 88666
- 167 + 88499 = 88666
- 173 + 88493 = 88666
- 197 + 88469 = 88666
- 239 + 88427 = 88666
Showing the first eight; more decompositions exist.
