Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54978, here are decompositions:
- 5 + 54973 = 54978
- 19 + 54959 = 54978
- 29 + 54949 = 54978
- 37 + 54941 = 54978
- 59 + 54919 = 54978
- 61 + 54917 = 54978
- 71 + 54907 = 54978
- 97 + 54881 = 54978
Showing the first eight; more decompositions exist.
