Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534976, here are decompositions:
- 97 + 31534879 = 31534976
- 103 + 31534873 = 31534976
- 157 + 31534819 = 31534976
- 223 + 31534753 = 31534976
- 307 + 31534669 = 31534976
- 379 + 31534597 = 31534976
- 433 + 31534543 = 31534976
- 547 + 31534429 = 31534976
Showing the first eight; more decompositions exist.
