Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526978, here are decompositions:
- 37 + 31526941 = 31526978
- 79 + 31526899 = 31526978
- 97 + 31526881 = 31526978
- 229 + 31526749 = 31526978
- 331 + 31526647 = 31526978
- 547 + 31526431 = 31526978
- 607 + 31526371 = 31526978
- 619 + 31526359 = 31526978
Showing the first eight; more decompositions exist.
