Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10500, here are decompositions:
- 13 + 10487 = 10500
- 23 + 10477 = 10500
- 37 + 10463 = 10500
- 41 + 10459 = 10500
- 43 + 10457 = 10500
- 47 + 10453 = 10500
- 67 + 10433 = 10500
- 71 + 10429 = 10500
Showing the first eight; more decompositions exist.
