Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77580, here are decompositions:
- 7 + 77573 = 77580
- 11 + 77569 = 77580
- 17 + 77563 = 77580
- 23 + 77557 = 77580
- 29 + 77551 = 77580
- 31 + 77549 = 77580
- 37 + 77543 = 77580
- 53 + 77527 = 77580
Showing the first eight; more decompositions exist.
