Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57972, here are decompositions:
- 29 + 57943 = 57972
- 71 + 57901 = 57972
- 73 + 57899 = 57972
- 113 + 57859 = 57972
- 163 + 57809 = 57972
- 179 + 57793 = 57972
- 181 + 57791 = 57972
- 191 + 57781 = 57972
Showing the first eight; more decompositions exist.
