Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57978, here are decompositions:
- 5 + 57973 = 57978
- 31 + 57947 = 57978
- 61 + 57917 = 57978
- 79 + 57899 = 57978
- 97 + 57881 = 57978
- 131 + 57847 = 57978
- 139 + 57839 = 57978
- 149 + 57829 = 57978
Showing the first eight; more decompositions exist.
