Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88816, here are decompositions:
- 3 + 88813 = 88816
- 5 + 88811 = 88816
- 17 + 88799 = 88816
- 23 + 88793 = 88816
- 149 + 88667 = 88816
- 173 + 88643 = 88816
- 227 + 88589 = 88816
- 269 + 88547 = 88816
Showing the first eight; more decompositions exist.
