Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57780, here are decompositions:
- 7 + 57773 = 57780
- 29 + 57751 = 57780
- 43 + 57737 = 57780
- 53 + 57727 = 57780
- 61 + 57719 = 57780
- 67 + 57713 = 57780
- 71 + 57709 = 57780
- 83 + 57697 = 57780
Showing the first eight; more decompositions exist.
