Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57740, here are decompositions:
- 3 + 57737 = 57740
- 13 + 57727 = 57740
- 31 + 57709 = 57740
- 43 + 57697 = 57740
- 61 + 57679 = 57740
- 73 + 57667 = 57740
- 103 + 57637 = 57740
- 139 + 57601 = 57740
Showing the first eight; more decompositions exist.
