Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 577780, here are decompositions:
- 23 + 577757 = 577780
- 29 + 577751 = 577780
- 41 + 577739 = 577780
- 59 + 577721 = 577780
- 113 + 577667 = 577780
- 167 + 577613 = 577780
- 179 + 577601 = 577780
- 191 + 577589 = 577780
Showing the first eight; more decompositions exist.
