Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76780, here are decompositions:
- 3 + 76777 = 76780
- 23 + 76757 = 76780
- 47 + 76733 = 76780
- 83 + 76697 = 76780
- 101 + 76679 = 76780
- 107 + 76673 = 76780
- 113 + 76667 = 76780
- 131 + 76649 = 76780
Showing the first eight; more decompositions exist.
