Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170784, here are decompositions:
- 7 + 170777 = 170784
- 11 + 170773 = 170784
- 17 + 170767 = 170784
- 23 + 170761 = 170784
- 43 + 170741 = 170784
- 73 + 170711 = 170784
- 83 + 170701 = 170784
- 137 + 170647 = 170784
Showing the first eight; more decompositions exist.
