Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71788, here are decompositions:
- 11 + 71777 = 71788
- 47 + 71741 = 71788
- 89 + 71699 = 71788
- 191 + 71597 = 71788
- 239 + 71549 = 71788
- 251 + 71537 = 71788
- 317 + 71471 = 71788
- 359 + 71429 = 71788
Showing the first eight; more decompositions exist.
