Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57440, here are decompositions:
- 13 + 57427 = 57440
- 43 + 57397 = 57440
- 67 + 57373 = 57440
- 73 + 57367 = 57440
- 109 + 57331 = 57440
- 139 + 57301 = 57440
- 157 + 57283 = 57440
- 181 + 57259 = 57440
Showing the first eight; more decompositions exist.
