Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170788, here are decompositions:
- 11 + 170777 = 170788
- 29 + 170759 = 170788
- 47 + 170741 = 170788
- 179 + 170609 = 170788
- 251 + 170537 = 170788
- 347 + 170441 = 170788
- 419 + 170369 = 170788
- 461 + 170327 = 170788
Showing the first eight; more decompositions exist.
