Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542446, here are decompositions:
- 7 + 31542439 = 31542446
- 73 + 31542373 = 31542446
- 283 + 31542163 = 31542446
- 379 + 31542067 = 31542446
- 409 + 31542037 = 31542446
- 433 + 31542013 = 31542446
- 457 + 31541989 = 31542446
- 547 + 31541899 = 31542446
Showing the first eight; more decompositions exist.
