Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178710, here are decompositions:
- 13 + 178697 = 178710
- 17 + 178693 = 178710
- 19 + 178691 = 178710
- 29 + 178681 = 178710
- 67 + 178643 = 178710
- 71 + 178639 = 178710
- 83 + 178627 = 178710
- 89 + 178621 = 178710
Showing the first eight; more decompositions exist.
