Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57990, here are decompositions:
- 13 + 57977 = 57990
- 17 + 57973 = 57990
- 43 + 57947 = 57990
- 47 + 57943 = 57990
- 67 + 57923 = 57990
- 73 + 57917 = 57990
- 89 + 57901 = 57990
- 109 + 57881 = 57990
Showing the first eight; more decompositions exist.
