Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176778, here are decompositions:
- 31 + 176747 = 176778
- 37 + 176741 = 176778
- 67 + 176711 = 176778
- 79 + 176699 = 176778
- 101 + 176677 = 176778
- 127 + 176651 = 176778
- 137 + 176641 = 176778
- 149 + 176629 = 176778
Showing the first eight; more decompositions exist.
