Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176680, here are decompositions:
- 3 + 176677 = 176680
- 29 + 176651 = 176680
- 71 + 176609 = 176680
- 83 + 176597 = 176680
- 89 + 176591 = 176680
- 107 + 176573 = 176680
- 131 + 176549 = 176680
- 149 + 176531 = 176680
Showing the first eight; more decompositions exist.
