Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 786, here are decompositions:
- 13 + 773 = 786
- 17 + 769 = 786
- 29 + 757 = 786
- 43 + 743 = 786
- 47 + 739 = 786
- 53 + 733 = 786
- 59 + 727 = 786
- 67 + 719 = 786
Showing the first eight; more decompositions exist.
