Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57784, here are decompositions:
- 3 + 57781 = 57784
- 11 + 57773 = 57784
- 47 + 57737 = 57784
- 53 + 57731 = 57784
- 71 + 57713 = 57784
- 131 + 57653 = 57784
- 191 + 57593 = 57784
- 197 + 57587 = 57784
Showing the first eight; more decompositions exist.
