Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57984, here are decompositions:
- 7 + 57977 = 57984
- 11 + 57973 = 57984
- 37 + 57947 = 57984
- 41 + 57943 = 57984
- 61 + 57923 = 57984
- 67 + 57917 = 57984
- 83 + 57901 = 57984
- 103 + 57881 = 57984
Showing the first eight; more decompositions exist.
