Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534772, here are decompositions:
- 19 + 31534753 = 31534772
- 43 + 31534729 = 31534772
- 103 + 31534669 = 31534772
- 211 + 31534561 = 31534772
- 229 + 31534543 = 31534772
- 271 + 31534501 = 31534772
- 331 + 31534441 = 31534772
- 349 + 31534423 = 31534772
Showing the first eight; more decompositions exist.
