Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57428, here are decompositions:
- 31 + 57397 = 57428
- 61 + 57367 = 57428
- 79 + 57349 = 57428
- 97 + 57331 = 57428
- 127 + 57301 = 57428
- 157 + 57271 = 57428
- 331 + 57097 = 57428
- 439 + 56989 = 57428
Showing the first eight; more decompositions exist.
