Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53978, here are decompositions:
- 19 + 53959 = 53978
- 61 + 53917 = 53978
- 79 + 53899 = 53978
- 97 + 53881 = 53978
- 349 + 53629 = 53978
- 367 + 53611 = 53978
- 409 + 53569 = 53978
- 499 + 53479 = 53978
Showing the first eight; more decompositions exist.
