Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77646, here are decompositions:
- 5 + 77641 = 77646
- 29 + 77617 = 77646
- 59 + 77587 = 77646
- 73 + 77573 = 77646
- 83 + 77563 = 77646
- 89 + 77557 = 77646
- 97 + 77549 = 77646
- 103 + 77543 = 77646
Showing the first eight; more decompositions exist.
