Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57144, here are decompositions:
- 5 + 57139 = 57144
- 13 + 57131 = 57144
- 37 + 57107 = 57144
- 47 + 57097 = 57144
- 67 + 57077 = 57144
- 71 + 57073 = 57144
- 97 + 57047 = 57144
- 103 + 57041 = 57144
Showing the first eight; more decompositions exist.
