Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534904, here are decompositions:
- 31 + 31534873 = 31534904
- 73 + 31534831 = 31534904
- 103 + 31534801 = 31534904
- 151 + 31534753 = 31534904
- 307 + 31534597 = 31534904
- 421 + 31534483 = 31534904
- 463 + 31534441 = 31534904
- 571 + 31534333 = 31534904
Showing the first eight; more decompositions exist.
