Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171662, here are decompositions:
- 3 + 171659 = 171662
- 79 + 171583 = 171662
- 103 + 171559 = 171662
- 109 + 171553 = 171662
- 181 + 171481 = 171662
- 193 + 171469 = 171662
- 223 + 171439 = 171662
- 409 + 171253 = 171662
Showing the first eight; more decompositions exist.
